Given:

Principal (P) = ₹80,000

Rate (r) = 10%

Time (t) = 2 years

Formula used:

A = P(1 + r/100)t

Compound Interest (CI) = A - P

Calculation:

A = 80000(1 + 10/100)2

⇒ A = 80000(1 + 0.1)2

⇒ A = 80000(1.1)2

⇒ A = 96800

CI = A - P

⇒ CI = 96800 - 80000

⇒ CI = 16800

∴ The correct answer is option 2.
