Question

Principal = ₹4000 , rate = 7.5 % ,time = 2 years find the compound intrest and amount​

Answer 1

CI=P(1+(r/100)) ^n-P

CI=4000(1+(7.5/100)) ^2-4000

CI=4000*1.075*1.075-4000

CI=4622.5-4000

CI=622.5

Answer 2

Solution :-

Given :
Principal = p = ₹4000
Rate = r = 7.5 % ,
Time = t = 2 years


Find the Amount (A) :-

A = p(1 + r)^t
A = 4000(1 + 7.5%)²
A = 4000(1 + 0.075)²
A = 4000(1.075)²
A = 4000 × 1.155625
A = 4622.5


Find the compound interest (C.I) :-

C.I = A - p
C.I = 4622.5 - 4000
C.I = 622.5


Hence,
Amount = ₹ 4622.5
Compound Interest = ₹ 622.5
