Solution

The sum which will earn a simple interest of ₹ 126 in 2 years at 14% per annum is ₹ 450.

Explanation:

From the question, It is given that,

SI = ₹ 126

Time = 2 years

Rate = 14%

Then, we know the formula of simple interest I = `(P xx R xx T)/100`

126 = `(P xx 14 xx 2)/100`

P = `12600/(14 xx 2)`

P = ₹ 450
