Correct Answer: 10800
Correct Answer: Rs. 4,000
Explanation:
Let sum invested @ 5% be P1, @ 6% be P2 then @ 9% =17200-(P1+P2)
So according to question
P1*5*2/100 = P2*6*2/100 or P1 = (6/5) P2
Also P2*6*2/100 = [17200-(P1+P2)]*9*2/100
Or 2 P2 = [17200?(11/5)P2] * 3
Or (2 + 33/5)P2 = 17200 * 3
P2 = 17200 * 3 * 5 / 43 = 6000
So P1 = 6/5 P2 = 7200
So Sum invested @ 9% = 17200?(6000+7200) = Rs 4000
