#### 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.
