Question

In how much time a principal amount of rs. 3200 with a rate of 8% will become rs. 3840. Hiii guys the correct answer is 5/2 years.

Answer 1

Hey Mate..!!

Here's Your Answer..!!

Principal ( p ) = Rs 3200

Amount ( A ) = Rs. 3840

Rate of interest ( r ) = 8%

Time = t years

Simple interest ( I ) = A - p

I = 3840 - 3200

= Rs 640

t = ( 100 × I )/pr

= ( 100 × 640 ) / ( 3200 × 8 )

= $\frac{5}{2}$ years

= $2 \frac{1}{2}$years

Hope This Helps..!!
