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
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. Loss on cost = (10 ÷ 110) × 100 = 9 1/11 %.

Correct answer: (B) 7.5 m
Correct answer: (C) 60 days
Correct answer: (C) 3/8
Let the fraction be x/y, so x + y = 11. Of the options only 3/8 meets that (3 + 8 = 11), and adding 1 to the numerator and taking 2 from the denominator gives 4/6 = 2/3, which satisfies the second condition. The digits of 5/6 and 6/5 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 is 4π × the luminous intensity. With an intensity of 2 candela the flux is 4π × 2 = 8π lumen.

Correct answer: (E) None of the above
z₁ = 2 − i और z₂ = 1 + i रखने पर z₁² = 3 − 4i, z₂² = 2i, अतः अंश = 3 − 4i + 2i + 1 = 4 − 2i। हर = (2 − i) − (1 + i) + i = 1 − i। अब (4 − 2i)/(1 − i) को (1 + i) से गुणा-भाग करने पर (6 + 2i)/2 = 3 + i मिलता है, जो 8, 12 या 16 में से कोई नहीं है। आयोग की कुंजी में विकल्प A (8) है, पर गणना से उत्तर 'इनमें से कोई नहीं' बनता है।
