If the difference between the compound interest and the simple interest on a certain sum for 2 yr at 8% per annum is RS. 32, then the sum is

A) RS.5000
B) RS.5500
C) RS.6000
D) RS.5250

Correct Answer:

A) RS.5000

Description for Correct answer:
Given, R = 8%, D = RS. 32 and P = ?

By formula, D = \( \Large P \left(\frac{R}{100}\right)^{2} \)

=> 32 = \( \Large P \left(\frac{8}{100}\right)^{2} \)

P = \( \Large \frac{32\times 100\times 100}{8\times 8} \) =RS.5000
