Correct answer: (A) 180
The smallest three-digit number divisible by 5 is 100 and the largest is 995. The count of terms = (995 − 100) ÷ 5 + 1 = 179 + 1 = 180.
Correct answer: (A) 60·5
Each bracket becomes (1 + 1/n) = (n+1)/n, so the product is (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. The value is 121/2 = 60·5.
Correct answer: (A) 3 hr 20 min
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. The loss per cent on the cost price = (10 ÷ 110) × 100 = 100/11 = 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, 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 PbO.
Correct answer: (A) Lithium
Across a period the nuclear charge grows and the electrons are pulled in harder, so the atomic radius falls from left to right. Of lithium, beryllium and boron, lithium stands furthest left, so its radius is the largest.
