The compound interest accrued on an amount of Rs. 25,500 at the end of three years is Rs. 8,440.5.What would be the simple interest accrued on the same amount at the same rate in the same period? a) Rs. 5,450/- b) Rs. 8,750/- c) Rs. 4,350/- d) Rs. 3,650/- e) Rs. 7,650/- 

1 Answer

Answer :

A = P + Interest

= 25500 + 8440.5 = 33940.5

A = P + 1 + (R/100)^3

33940.5 = 25500 a + R/100)^3

a + R/100)^3 = 33940.5 / 25500

a + R/100)^3 = 1.331

a + R/100)^3 = a.1)^3

1 + R/100 = 1.1

R/100 = 1.1 - 1

R/100 = 0.1

R = 0.1×100

R = 10%

Simple Interest = Principle × Rate × Time / 100

= 25500 × 10 × 3/100 = 7650

Answer: e)
