#### Question

A principal amounts to ₹13924 in 2 years by compound interest at 18 p.c.p.a. Find the principal.

#### Solution

Here, P = Principal

A = ₹ 13924

R = 18 %

N = 2 years

A = P `(1 + "R"/100)^"N"`

= 13924 = P `(1 + 18/100)^2`

= 13924 = P `(1 + 9/50)^2`

= 13924 = P `(59/50)^2`

= P = `(13924 xx 50 xx 50)/(59 xx 59)`

= P = 10000

Hence, the principal is ₹ 10000.
