\small{\boxed{\boxed{\bold{Information~provided~to~us:}}}}

Principal, P = ₹ 4000

Rate Of Interest, R = 9 ( 1 / 2 ) % = 19 / 2 % p.a.

Time, T = 2 years

\small{\boxed{\boxed{\bold{Answer:}}}}

Amount = ₹ 4796.10
Compound Interest = ₹ 796.10

\small{\boxed{\boxed{\bold{Step-By-Step~ Explanation:}}}}

Amount, A = P * ( 1 + R/100 ) ^ T
A = 4000 ( 1 + 19/200 ) ^ 2
A = 4000 ( 219 / 200 ) ^ 2
A = 4000 * 219/200 * 219/200
A = 20 * 219 * 219/200
A = 219 * 219/10
A = 47961 / 10
A = ₹ 4796.10

Hence, Amount = ₹ 4796.10
Compound Intrest, CI = A - P
CI = ₹ 4796.10 - ₹ 4000
CI = ₹ 796.10
Compound Interest = ₹ 796.10

A = 4000 ( 1 + 19/200 ) ^ 2

A = 4000 ( 219 / 200 ) ^ 2

A = 4000 * 219/200 * 219/200

A = 20 * 219 * 219/200

A = 219 * 219/10

A = 47961 / 10

A = ₹ 4796.10

Hence, Amount = ₹ 4796.10

Compound Intrest, CI = A - P

CI = ₹ 4796.10 - ₹ 4000

CI = ₹ 796.10

Compound Interest = ₹ 796.10
