Correct answer: B. B and C Onlyकेवल B और C
Explanation
A: 25 % of 1600 = 400 and 5 % of 400 = 20, not 50 — false. B: 33⅓ % of 10,000 = 3333.33 and 0.15 % of that = 5 — true. C: SI = P×R×T/100 → 5400 = 15000×R×3/100 → R = 12 % — true. D: x/3 = y/4 = z/5 gives x : y : z = 3 : 4 : 5, not 2 : 3 : 7 — false. Hence B and C Only.A: 1600 का 25% = 400 और 400 का 5% = 20, 50 नहीं — असत्य। B: 10,000 का 33⅓ % = 3333.33 तथा इसका 0.15 % = 5 — सत्य। C: साधारण ब्याज = मूलधन×दर×समय/100 → 5400 = 15000×R×3/100 → R = 12 % — सत्य। D: x/3 = y/4 = z/5 से x : y : z = 3 : 4 : 5 मिलता है, 2 : 3 : 7 नहीं — असत्य। अतः केवल B और C।More Mathematical Reasoning and Aptitude questions
