S.I

$= ) \: \frac{p \times r \times t}{100} \\ = ) \: \frac{100 \times 10 \times 1}{100}$

=) ₹10

Amount at the end of the 1st year = ₹(100+10) = ₹110

Principal for the 2nd year = ₹110

Rate = 10% per annum

S.I

$= ) \: \frac{p \times r \times t}{100} \\ = ) \: \frac{110 \times 10 \times 1}{100}$

Amount at the end of the 2nd year = ₹(110 + 11) = ₹121

Compound Interest = ₹(121 - 100) = ₹21
