Correct answer: A. Rs. 650, Rs. 900रु. 650, रु. 900
Explanation
Let x be lent at 8%. 0.08x + 0.06(1550 − x) = 106 → 0.02x = 106 − 93 = 13 → x = 650. So Rs. 650 at 8% and Rs. 900 at 6%. Check: 52 + 54 = 106.मान लीजिए x राशि 8% पर दी गई। 0.08x + 0.06(1550 − x) = 106 → 0.02x = 106 − 93 = 13 → x = 650। अतः 8% पर रु. 650 और 6% पर रु. 900। जाँच: 52 + 54 = 106।More Mathematical Reasoning and Aptitude questions
