Answer 2

Explanation:-

Given,

interest for a annum-10%

principle amount-4000 Rs.

time-2 1/2 years

formula for compound interest is-

A=P(1+rate%/100)^no of year

4000(110/100)^2

=4000×121/100

=4840 Rs.

But it is is given 2 and a HALF years..so-

compound interest for 2years- 840Rs

for half-year it will be- 210 Rs

.so the total amount-Rs.4840+Rs.210

=Rs.5050Rs

C.I=5050-4000

=Rs.1050 Rs.
