the compound interest on rs 2000 for 2 yr at the rate of 8 per cent per annum when the interest is compound annually is​

Answer 1

Answer:

Here is the answer.

Rs. 142.40

Given, P= Rs. 2000, r1 =4% p.a. for 1st year, r2 =3% p.a. for 2nd year

∴A=P(1+100r1)(1+100r2)

=2000(1+1004)(1+1003)

= Rs. (2000×2526×100103)= Rs. 2142.40

∴ C.I. = Rs. 2142.40− Rs. 2000= Rs. 142.40
