Answer 2

$\huge\color{lime}{Question:-}$

what sum of money will amount to rupees 1170 in three years at 10% per annum simple interest ?

$\huge\color{cyan}{Solution:-}$

Here, S.I. = 1700, P = 2 years, R = 10% p.a.

Using simple interest formula, we have

S.I. = (PxNxR)/100

(a)

P = (S.I. x 100)/(N x R)

= (1700 x 100)/(2 x 10)

= 8500

Therefore, sum (P) = Rs. 8500

(b)

A=P(1+ r/2x100)2n

= 8500(1 + 10/200)2

= 8500(21/20)2

= Rs. 9371.25

Compound Interest (C.I.) = A - P = 9371.25 - 8500 = Rs. 871.25
