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

(a) ₹394

(b) ₹395

(c) ₹450

(d) ₹540

**Solution:**

Given, the simple interest is ₹126.

__Number__ of years = 2years

Rate of interest = 14%

We have to find the sum.

__Interest__, I = P × R × T/100

According to the question,

I = ₹126

T = 2 years

R = 14%

126 = P × 14 × 2/100

126 = P × 28/100

126 × 100 = P × 28

P = 126 × 100/28

= 12600/28

= 6300/14

= 900/2

= 450

Therefore, the sum is ₹450.
