Question

1. Simple interest on a sum of
money at the end of 4 years is
1/3 of the sum itself. What will
be the rate percent per
annum?​

Answer 1

Step-by-step explanation:

Let the principal be then S. I. Will be P/3

$rate = \frac{simple \: inerest \times 100}{principal \times time}$

$rate \: = \frac{ \frac{p}{3} \times 100}{p \times 4}$

$rate = \frac{100}{12 } = \frac{25}{3} = 8 \times \frac{1}{3}$
