Question

A sum of money is invested for 3 years at 11% p.a. If it is invested for 5 years, the interest
increases by 5500. Find the sum of money​

Answer 1

Answer:

Rs 25000

Step-by-step explanation:

Let the amt be x and interest be a.

For 3 yrs,

x=(a*100)/11*3

Put value of a to a=33x/100

Now for 5 yrs,

x=[(a+5500)*100]/11*5

Put value of a here, we will then get,

55x=33x+550000

Solving it x=25000
