Question

find the compound interest on Rs . 6500 at 12 % p.a for two years​

Answer 1

Answer:

Given,

Principal(P) = ₹ 6500

rate (r) = 12℅

time (n) = 2 years

By formula,

Amount (A) = P × ( 1 + r/100) ^n

= 6500 × ( 1 + 12/100) ^2

= 6500 × {(100 ×1) + (12×1) / 100}^2

= 6500 × {(100 + 12) / 100}^2

= 6500 × (112/100)^2

= 6500 × (28/25) ^2

= (6500 × 28 × 28) / (25 × 25)

= 5096000/625

= 8153.6

Therefore,

Compound Interest (C.I) = A - P

= 8153.6 - 6500

= 1653.6 (ans)
