उत्तर

For 1st year
P = ₹8000
R = 10%
T = 1 year

I = `[8000 xx 10 xx 1]/100` = 800

A = ₹8000 + ₹800 = ₹8800
For 2nd year
P = ₹8800
R = 10%
T = 1 year

I = `[ 8800 xx 10 xx 1]/100`
Compound interest for 2nd years = ₹880

Amount after 2 years = ₹8800 + ₹880 = ₹9680.

Principal for the third year = ₹9680.

Interest for the third year = `₹(9680 × 10 × 1)/100`​ = ₹968.

Amount after 3 years = ₹9680 + ₹968 = ₹10648.

Hence, the compound interest for the second year on ₹8000 invested for 3 years at 10% p.a. is ₹880, and the sum due at the end of the third year is ₹10648.
