Question

a sum of rupees 1780 becomes rupees 2136 in 4 years. find the rate of interest.

Answer 1

Hi ,

Principal = ( P ) = Rs1780

Amount ( A ) = Rs2136

Time ( T ) = 4 years

Let the rate of interest = r

Simple interest ( I ) = A - P

I = Rs 356

r = ( 100I ) / PT

= ( 100 × 356 ) / ( 1780 × 4 )

= 5

Therefore ,

r = 5%

I hope this helps you.
