Find the time period when Rs 6540 yields an amount of 8238.50 at 8 %

..AnsweR..

Given ,

> Principle = Rs 6540

> Amount = Rs 8238.50

> Rate = 8 %

> Time = ?

At first ,

> Amount = Principle + Interest

> 8238.50 = 6540 + Interest

> 8238.50 - 6540 = Interest

> Interest = 1680.50

•°• we got , Interest = Rs 1680.50

•°• Time =

> S.I. = ( P × T × R ) / 100

> 1680.50 = ( 6540 × T × 8 ) / 100

> 1680.50 = 523.20 × T

> T × 523.20 = 1680.50

> T = 1680.50 / 523.20

> T = 168050 / 52320 [ multiply both side by 100 ]

> T = 3.21

•°• Time = 3 years , 21 months

i.e. = 4 years and 9 months ✓ Ans..
