A man invested 1/3 of his capital at 7%, 1/4 at 8% and remainder at 10%. If his annual income is Rs. 561, the capital is?

Question

Accepted Answer

Let the capital be Rs. P, then (P/3) x (7/ 100) + (x/4) x (8/100) + [P - (P/3 + P/4)] x 10/100 = 561 ⇒ 7P/300 + P/50 + P/24 = 561 ⇒ 42P + 36P + 75P = 1009800 P = 1009800/153 = 6600
