    2. ₹ 2052.50
    3. ₹ 2025.20
    4. ₹ 2501.20
Correct Option: A

Given Here , Principal = ₹ 32,000 , C.I. - S.I. = ? , Time = 4 years , Rate = 10%

S.I. =
Principal × Time × Rate
100

S.I. =
32000 × 4 × 10
= ₹ 12800
100

C.I. = P 1 +
R
4 − 1
100

C.I. = 32000 1 +
10
4 − 1
100

C.I. = 32000 [(1.1)4 – 1]
C.I. = 32000 (1.4641 – 1)
C.I. = 32000 × 0.4641= 14851.2
∴  Required difference = C.I. - S.I.
Required difference = 14851.2 – 12800 = ₹ 2051.2
