Question

find the amount and compound interest on a sum of 15625at 4 per annum for annum for 3 years compounded annually

Answer 1

Amount = P(1+r/100)^t

=15625(1+4/100)^3

=15625(104/100)^3

=15625×1.124

=17576

So, amount is 17576

and compound interest is 17576-15625

=1951

Answer 2

Hi mates...........
here is ur answer..........
⬇⬇⬇⬇⬇⬇⬇⬇
A= P ( 1+ r/100)^t

A= 15625 (1+ 4/100)^3

A= 15625 × 104/100 ×104/100 × 104/100

A= 26 × 26 × 26

A= Rs.17576

C.I= A - P

= 17576 - 15625

= Rs.1951
