Question

A sum of money lent out at simple interest amounts to Rs.2200 in one year and Rs.2800 in 4 years. Find the sum of money and the rate of interest. Please solve and answer...

Answer 1

Amount in 1 year= Rs.2200
Amount in 4 year= Rs.2800
SI of 3 year= (Amt in 4 yr)-(Amt in 1 yr)
= Rs. (2800-2200)= Rs.600
SI of 1 year= Rs.200
Amt of 1 year= Rs.2200
Sum=(Amt-SI)
=Rs.(2200-200)= Rs.2000
Rate= (SI*100)/(P*T)
= (200*100)/(2000*1)
= 20000/2000= 10%
