Hi ,

Principal ( p ) = Rs 400


Amount ( A ) = Rs 520

Simple interest ( I) = A - P

I = 520 - 400

I = Rs 120

Time ( t ) = 5 Years

Let the rate of interest = r %

We know that

( ptr ) / 100 = I

t = ( 100 × I ) / pt

t = ( 100 × 120 ) / ( 400 × 5 )

t = 6 years

I hope this helps you.

Step-by-step explanation:

principal=400

amount=520

simple interest=amount - principal

simple interest=520-400=120

R=S.I×100÷P×t

120×100÷400×5

6%p.a
