The Brainliest Answer!

solution :

There is a mistake in ur question .

Given

C.I - S.I = 157.5 .............. (1)

time = 3 years

rate of interest = 8% per annum

let the sum be = x

therefore ,

S.I = principal *R*T/100

= x*8*3/100h8

=24x/100

Amount = x (1+8/100)³

= x (100+8/100)³

=x(108/100)³

= x(1.25)

C.I = amount - sum

= 1.25x - x

Using 2nd and 3rd in 1st equation , we get

0.25 x - 0.24x = 157.5

.1 x = 157.5

or x/10 = 157.5

x= 1575

hence the sum is 1575 rupees

Hope this helps you!!

Please mark as best !!

Thank yOU!!!
