Correct answer: (A) 180
The smallest three-digit multiple of 5 is 100 and the largest is 995. The count is (995 − 100) ÷ 5 + 1 = 179 + 1 = 180.
Correct answer: (A) 60·5
Turn each bracket into a fraction: (1 + 1/n) = (n+1)/n. The product becomes (3/2) × (4/3) × (5/4) × … × (121/120). Each numerator cancels the next denominator, leaving only the first denominator 2 and the last numerator 121. So the value is 121/2 = 60·5.
Correct answer: (A) 3 hr 20 min
The first 120 km at 90 km/hr takes 4/3 hours, that is 80 minutes. The remaining 80 km at 40 km/hr takes 2 hours, that is 120 minutes. The total is 200 minutes = 3 hours 20 minutes.
Correct answer: (A) 9 1/11%
Take the selling price as 100. A 10% loss means a loss of 10, so the cost price was 110. Loss on cost = (10 ÷ 110) × 100 = 9 1/11 %.
Correct answer: (B) Day 2
Compare the fractions: two-fifths is 0·4, three-fourths is 0·75 and 9/16 is 0·5625. He began each day with the same number, so the largest fraction means the most delivered—day 2.
Correct answer: (B) 7·5 m
The total cost is ₹810 at ₹4·50 a metre, so the carpet is 810 ÷ 4·50 = 180 metres long. Its width is 75 cm, that is 0·75 m, so the area is 180 × 0·75 = 135 m². The breadth of the room = 135 ÷ 18 = 7·5 m.
Correct answer: (C) 60 days
Add the day's work: together A and B do 1/15 of the task and A alone 1/20. So B's day's work is 1/15 − 1/20 = (4 − 3)/60 = 1/60, and B alone would take 60 days.
Correct answer: (C) 3/8
Take the fraction as x/y, so x + y = 11. Among the options only 3/8 meets that (3 + 8 = 11), and adding 1 to the numerator while subtracting 2 from the denominator gives 4/6 = 2/3, which is the second condition. In 5/6 and 6/5 the two numbers do not add to 11 at all.
Correct answer: (C) 8π lumen
An isotropic source throws light equally in every direction, so the total luminous flux = 4π × luminous intensity. The intensity here is 2 candela, so the flux is 4π × 2 = 8π lumen.
Correct answer: (B) Bernoulli’s principle
In a spray bottle the air moves fast, which lowers the pressure there, so the liquid is drawn up the tube and comes out as a spray. Pressure falling where the speed is high is Bernoulli's principle.
Correct answer: (A) White lead
The trade name of basic lead carbonate is white lead, once used in white paint. Red lead is Pb₃O₄ and litharge is PbO.
Correct answer: (A) Lithium
Moving left to right across a period the nuclear charge rises and the atomic radius shrinks. Lithium lies furthest left of the three, so its radius is the largest.

Correct answer: (A) It contains very rare species of plants and animals
Correct answer: (D) More than one of the above
