Question

In what time will Rs. 400 amount to650 at 5% per annum S.I.​

Answer 1

Step-by-step explanation:

We have principal =Rs.400

It will amount to Rs.448

since simple interest = Amount − principal

=448−400

S.I=Rs.48

Rate of interest =4% per annum

We knew S.I=

100

P×R×T

48=

100

400×4×T

16T=48

T=3

So in 3 years the sum of Rs. 400 will amount to Rs. 448
