Question

find the compound interest on 20000 rupees for 2 and half year at 10% per annum compounded yearly​

Answer 1

Here is the method to solve this

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

= 20000 ( 1 + 10/100 )^2 × ( 1 +5/100 )^1

=20000 ( 121/100 ) × (105/100)

=25410 Rs.

Compound Interest = Amount- Principal

= 25410-20000

=5410 Rs.

Answer is 5410 Rs.
