What rate gives ₹280 as interest on a sum of ₹56,000 in 2 years?

Solution:

Let us assume the rate of interest to be R.

Let us use the formula for simple interest.

So, Simple Interest = [Principal × Rate × Time] / 100

Here Simple interest , Time and Principal is given as Rs. 280, 2 years and Rs. 56000 respectively.

On substituting the above values we get,

⇒ 280 = [56000 × R × 2] / 100

⇒ R = [280 × 100] / 56000 × 2

= 0.25%

So, the rate of interest is 0.25%
