Find the difference (in Rs) in the interest earned on Rs 10,00,000 at 10% in 1 year compounded annually and semi-annually.

Show answer & explanation

Correct answer: D

Explanation

  The correct answer is option 4 i.e. 2500

Understanding

Application

P = Rs. 1000000

R = 10%

T = 1 year

When the interest is compounded annually:

A = 1000000 × (1 + 10/100)

= 1100000

And

When the interest is compounded semi-annually:

A = 1000000 × (1 + 5/100)2

= 1102500

So,

Difference of interest = 1102500 – 1100000 = Rs. 2500
