Answer Key

Every answer carries its method — read the explanation even for answers you got right.

1. 1. A — The denominator 8 is the LCM of 4 and 8, so 3/4 becomes 6/8; then 6/8 + 1/8 = 7/8.
2. 2. A — 0.25 means 25 hundredths = 25/100. Dividing the top and bottom by 25 gives 1/4.
3. 3. D — 2³ means 2 × 2 × 2 = 8 and 3² means 3 × 3 = 9; 8 + 9 = 17.
4. 4. A — Speed = distance ÷ time = 240 ÷ 4 = 60 km/h.
5. 5. A — Add them: 12 + 18 + 24 + 30 = 84. Divide by the number of values: 84 ÷ 4 = 21.
6. 6. D — Find one pen first: 75 ÷ 5 = Rs 15. Then 8 × 15 = Rs 120.
7. 7. A — List the multiples of the larger number: 8, 16, 24 — and 24 is the first that 6 also divides exactly.
8. 8. A — Factors of 18: 1, 2, 3, 6, 9, 18. Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24. The largest shared factor is 6.
9. 9. D — A quarter means 25/100 × 480 = 480 ÷ 4 = 120.
10. 10. D — Perimeter = 2 × (length + width) = 2 × (12 + 7) = 2 × 19 = 38 cm.
11. 11. A — Area of a square = side × side = 9 × 9 = 81 cm².
12. 12. D — 21 = 3 × 7, 27 = 3 × 9 and 33 = 3 × 11, so all three have factors. 29 is divisible only by 1 and itself.
13. 13. A — Subtract 7 from both sides: x = 19 − 7 = 12.
14. 14. D — Divide both parts by their HCF, 6: 18 ÷ 6 = 3 and 24 ÷ 6 = 4, giving 3 : 4.
15. 15. D — One egg costs 156 ÷ 12 = Rs 13, so 5 eggs cost 5 × 13 = Rs 65.
16. 16. D — Give them a common denominator of 30: 15/30, 20/30, 18/30 and 25/30. The largest is 5/6.
17. 17. A — Profit = 10% of 500 = Rs 50, so the selling price is 500 + 50 = Rs 550.
18. 18. D — A straight line turns through half a full turn, and a full turn is 360°, so the straight angle is 180°.
19. 19. D — Adding a positive moves the number line to the right: from −8, fifteen steps forward lands on 7.
20. 20. D — 1 hour 30 minutes = 1.5 hours, and 45 ÷ 1.5 = 30 km/h.
21. 21. D — Discount = 10% of 700 = Rs 70, so the buyer pays 700 − 70 = Rs 630.
22. 22. D — Multiply as whole numbers: 6 × 5 = 30. The two factors have one decimal place each, so the answer takes two: 0.30, which is 0.3.
23. 23. A — Multiples of 6 are 6, 12, 18, 24 — and 12 is the first one that 4 divides exactly.
24. 24. D — The ratio has 3 + 5 = 8 parts, so one part is 3600 ÷ 8 = Rs 450 and A gets 3 × 450 = Rs 1,350.
25. 25. A — The fence runs round the boundary, which is 4 × 15 = 60 m. At Rs 20 a metre that is 60 × 20 = Rs 1,200.
26. 26. D — With he, she or it the present simple verb takes -s: he goes. The other options are missing either the ending or a helping verb.
27. 27. A — A cat sitting below a table is under it. On the table means on top of it, which is the opposite of hiding.
28. 28. D — Elephant begins with a vowel sound, and an is used before vowel sounds: an elephant.
29. 29. C — The subject is one, not friends, so the verb is singular: One of my friends is a doctor.
30. 30. D — Brave and courageous both describe someone who faces danger without giving way; coward means the opposite.
31. 31. C — Ancient means very old, so its opposite is modern — belonging to the present time. Old and historic are synonyms, not opposites.
32. 32. A — The correct spelling has one c and two s's: necessary. Remember it by the sound of the middle syllable.
33. 33. D — A direct question always ends with a question mark, not a full stop, comma or exclamation mark.
34. 34. C — Good is irregular: good — better — best. Gooder and more good are not English forms.
35. 35. C — The time word yesterday shows a finished action in the past, which takes the past simple: completed.
36. 36. D — The phrase comes from putting weapons away, so it means ending a quarrel and making peace.
37. 37. A — In the passive the object becomes the subject and the verb takes was plus the past participle: was broken.
38. 38. D — The author writes the book; the publisher prints and sells it and the editor corrects it.
39. 39. A — Dawn is the first light of morning, so an empty platform at that hour is explained by the early time — the passage says nothing about the other reasons.
40. 40. A — The two ideas pull in opposite directions, and but is the conjunction that sets them against each other.
41. 41. C — The collective noun for lions is a pride. Herd is for cattle, flock for birds and sheep, swarm for bees.
42. 42. D — At the moment signals an action happening now, which takes is/are plus the -ing form: are playing.
43. 43. D — Beau-ti-ful gives three beats, so three syllables.
44. 44. C — With she the helper is does not, written doesn't, and the main verb stays plain: doesn't like.
45. 45. B — Un- reverses the meaning of the word it joins, so unkind means not kind.
46. 46. A — The levels build upward: cells make tissues, tissues make organs, organs make systems. So the level just above cells is tissue.
47. 47. A — Photosynthesis needs sunlight as the energy source; carbon dioxide and water are the raw materials, but without light the process cannot start.
48. 48. C — The heart is a muscular pump; the lungs take in air and the kidney filters waste. Only the heart drives blood round the body.
49. 49. A — Water freezes at 0 °C and boils at 100 °C at normal air pressure. 4 °C is simply the temperature at which water is densest.
50. 50. B — Burning needs oxygen — nothing burns in nitrogen alone, and carbon dioxide is what fire extinguishers throw on a flame to put it out.
51. 51. B — Plant-eating animals are herbivores — the first consumers in a food chain. Carnivores eat other animals, and producers are the plants themselves.
52. 52. B — Cooling turns vapour into droplets — condensation, which forms clouds and dew. Evaporation is the opposite change, liquid to vapour.
53. 53. B — Earth behaves like a giant magnet, so a suspended magnet lines up with its magnetic field: one end towards north and the other towards south.
54. 54. B — Saliva begins breaking down starch as soon as food is chewed, so the mouth is where digestion starts; the stomach continues it later.
55. 55. C — Sound needs particles to carry its vibrations, and they sit closest together in a solid, so the speed is highest in steel — while a vacuum carries no sound at all.
56. 56. C — Roots take in water and dissolved minerals from the soil, and the stem then carries them upward to the leaves.
57. 57. B — Boiling the salty water and cooling the vapour leaves the salt behind, and the collected distillate is pure water. Filtration cannot separate dissolved salt.
58. 58. C — Opaque materials block light completely and form a shadow. Transparent materials let light through, and translucent ones scatter part of it.
59. 59. B — Gravity is the pull between the earth and an object, which is why a dropped ball falls and why we have weight.
60. 60. C — Vitamin C keeps gums and skin healthy, and its absence causes scurvy — bleeding gums and slow healing. Night blindness comes from a lack of vitamin A.
61. 61. C — The planets in order outwards are Mercury, Venus, Earth, Mars, so Mercury lies closest to the sun and is also the smallest.
62. 62. B — Rusting forms a new substance — iron oxide — and cannot be reversed simply, which makes it a chemical change. The others change only shape or state.
63. 63. C — Plants take in carbon dioxide and give out oxygen, which is the reverse of what animals do when they breathe.
64. 64. C — A screw is an inclined plane wound round a cylinder, which is why a small turning force can drive it deep into wood.
65. 65. A — A full adult set has 32 teeth, counting the four wisdom teeth. Children have 20 milk teeth.
66. 66. C — Metals are good conductors because free electrons carry heat quickly; air, water and wood are poor conductors and act as insulators.
67. 67. B — About four fifths of air is nitrogen, and oxygen is only about one fifth — a common misconception because oxygen is the gas our body needs.
68. 68. C — Insects take in air through tiny openings along the body called spiracles, which connect to air tubes inside. They have no lungs.
69. 69. B — Almost all energy on earth — from food to wind and rain — ultimately comes from the sun; coal and oil are stored sunlight from long ago.
70. 70. B — Vertebrates have a backbone and an internal skeleton; invertebrates do not. Mammals are only one group within the vertebrates.
71. 71. B — Kalima Tayyaba is the first — La ilaha illallah Muhammadur Rasulullah. Kalima Shahadat is the second, so the order matters here.
72. 72. B — The first revelation came when the Prophet (SAW) was forty, and the Quran continued to be revealed for about twenty-three years until his passing.
73. 73. A — Hazrat Muhammad (SAW) is Khatam-un-Nabiyyeen, the final Prophet; no Prophet comes after him, which is what the title itself declares.
74. 74. C — Taurat was revealed to Hazrat Musa (AS), Zabur to Hazrat Dawood (AS), Injeel to Hazrat Isa (AS), and the Quran to Hazrat Muhammad (SAW).
75. 75. D — Fasting in Ramzan is the fourth pillar of Islam. Shawwal is the month of the Eid that follows it, not a month of fasting.
76. 76. B — اردو میں مؤنث الفاظ کی جمع 'یں' کے ساتھ بنتی ہے، اس لیے 'کتاب' کی جمع 'کتابیں' ہے۔ 'کتابوں' کو حال کی حالت میں استعمال کیا جاتا ہے۔
77. 77. A — اندھیرے کے معنی روشنی کی کمی ہے، اس کا الٹ 'اجالا' ہے جو روشنی کی موجودگی بتاتا ہے۔ 'تاریک' تو اندھیرے کا ہم معنی لفظ ہے۔
78. 78. C — محنت اور کوشش دونوں ایک ہی معنی میں استعمال ہوتے ہیں۔ 'سستی' اور 'آرام' دونوں اس کے متضاد ہیں۔
79. 79. A — 'آنکھ کا تارا' بہت عزیز اور پیارے شخص کے لیے بولا جاتا ہے، نہ کہ بینائی سے متعلق کسی بات کے لیے۔
80. 80. B — یہ مقولہ کہتا ہے کہ ہر جگہ کے رسم و رواج کے مطابق اپنے آپ کو ڈھال لینا چاہیے۔ اس کا تعلق کپڑوں کی خرید و فروخت سے نہیں۔
81. 81. C — بہادر وہ ہے جو خطرے سے نہ بھاگے، اس کا الٹ 'بزدل' ہے جو ڈر کر پیچھے ہٹ جائے۔ 'دلیر' تو بہادر کا ہم معنی لفظ ہے۔
82. 82. B — 'استاد' مذکر ہے اور اس کی جمع 'اساتذہ' ہے، جو عربی قاعدے پر بنتی ہے۔ 'استادیں' استاد کے لیے کبھی مستعمل نہیں۔
83. 83. B — 'کتاب' میں چار حروف ہیں: ک، ت، ا، ب — یہ گنتی لفظ کے اصل رسم الخط کی ہے، آواز کے حصوں کی نہیں۔
84. 84. A — علم کے معنی جانکاری کے ہیں اور اس کا الٹ 'جہل' یعنی ناواقفیت ہے۔ 'دانائی' علم ہی کا قریبی معنی ہے، متضاد نہیں۔
85. 85. C — جملے میں 'نے' کے ساتھ فعل کا ماضی والا صیغہ 'کھایا' استعمال ہوا ہے، جو گزرے ہوئے وقت کو ظاہر کرتا ہے۔
86. 86. B — Each term is 3 more than the one before it, so 11 + 3 = 14. Checking the step in every gap is what makes a series reliable.
87. 87. C — These are the squares of 1, 2, 3 and 4, so the next term is 5 × 5 = 25.
88. 88. B — All the others are prime numbers with no factor except 1 and themselves, while 9 = 3 × 3, so 9 breaks the rule.
89. 89. B — The letters skip one alphabet each time — A, then C, then E, then G — so after G comes I.
90. 90. B — A book is the tool for reading and a fork is the tool for eating, so the pair must match in the same way: the object and its use.
91. 91. A — Every letter moves one step forward in the alphabet: C to D, A to B, T to U — so D, O, G become E, P, H.
92. 92. C — Ali stands above Bilal but below Danish, so the order is Danish, then Ali, then Bilal. The comparison is complete, so it can be decided.
93. 93. C — A right turn from north swings clockwise by a quarter turn, which lands on east. Left from north would give west.
94. 94. D — A circle, a square and a triangle are all flat two-dimensional shapes, while a cube has length, width and height — it is three-dimensional.
95. 95. B — Every term is double the term before it: 24 × 2 = 48. Adding the same amount each time would give a different series.
96. 96. B — Ahmad is himself one of his mother's sons, so the third son is Ahmad — the trick is that the question already names him.
97. 97. C — Compare letter by letter: after a-p-p, the fourth letter of appeal is e, which comes before l in apple, r in apricot or l in apply.
98. 98. D — The cow, goat and sheep all eat plants, while the lion eats meat — it is the only carnivore in the list.
99. 99. C — The series counts down by 2 each time, so 6 − 2 = 4.
