Question

In how many years will Rs 150 double itself at 4%simple interest?

Answer 1

Hi ,

Principal = P = Rs 150

Amount ( A ) = 2P = 2 × 150 = Rs 300

Rate of interest = R = 4%

Let the time = T years

A = P ( 1 + TR/100 )

300 = 150 ( 1 + 4T/100 )

300/150 = 1 + T/25

2 = 1 + T/ 25

2 - 1 = T/25

1 = T/25

25 = T

Therefore ,

Time = T = 25 years

I hope this helps you.
