Question

What sum will amount to ₹ 18544 in 4 years and 4 months at the rate of 12% per annum simple interest?

Answer 1

Step-by-step explanation:

A = 18544

T = 4 year 4 month

$4 \frac{4}{12} = 4 \frac{1}{3} = \frac{13}{3}$

R = 12%

Let us assume sum as x

$interest = \frac{ptr}{100} \\ = \frac{x \times 13 \times 12}{3 \times 100} \\ = \frac{13x}{25}$

Amount A = P + I

$18544 = x + \frac{13x}{25} \\ 18544 = \frac{38x}{25} \\ x = \frac{18544 \times 25}{38} = 12200$

Sum = ₹12200/-
