Question

P=3200,r=25%p.a,n=3years. Find the compound interest when it is compounded annually

Answer 1

Answer:

Compound Intrest = ₹3050

Step-by-step explanation:

P = ₹3200

R = 25%p.a.

n = 3years

C.I. = p × [(1 + r/100)^3 - 1]

= 3200 × [(1 + 25/100)^3 - 1]

= 3200 × [(1 + 1/4)^3 - 1]

= 3200 × [(4+1/4)^3 - 1]

= 3200 × [(5/4)^3 - 1]

= 3200 × [125/64 - 1]

= 3200 × [125 - 64/64]

= 3200 × 61/64

= 50 × 61

= 3050
