- C. Rs. 4,800
- D. Rs. 5000
- Correct Answer
- Rs. 4,000
ExplanationLet sum invested @ 5% be P1, @ 6% be P2 then @ 9% =17200-(P1+P2)So according to questionP1*5*2/100 = P2*6*2/100 or P1 = (6/5) P2Also P2*6*2/100 = [17200-(P1+P2)]*9*2/100Or 2 P2 = [17200?(11/5)P2] * 3Or (2 + 33/5)P2 = 17200 * 3P2 = 17200 * 3 * 5 / 43 = 6000So P1 = 6/5 P2 = 7200So Sum invested @ 9% = 17200?(6000+7200) = Rs 4000 - 1.
