Question

 A sum of money lent out at 9 % for 5 years produces twice as much interest as Rs. 9800 in 9/2 years at 10%. the money lent out is ....​

Answer 1

19600

Step-by-step explanation:

let P be the sum

step1-

I=P*N*R/100. = P*5*9/100

9P/20

step2-

I=P*N*R/100. = 9800*9/2*10/100 =9800*9*5/100

9800*45/100 twice then

2(9800*45/100) = 2(98*45) = 8820

both step1=step2

9P/20=8820

9P=176400

P=19600

The answer is 19600
