Question

Find the compound interest on 72000 for one year at a rate of 20% p.a., if the interest
is compounded quarterly.
​

Answer 1

Answer:

Rs. 15516.45

Step-by-step explanation:

Principal = Rs. 72000

Time = 1

Rate (per annum) = 20%

Rate (per quarter) = 20÷4 = 5%

Amount = 72000(1 + 5/100)^4 = (72000×105×105×105×105)÷(100×100×100×100) = 87,516.45

Compound Interest = Rs. 87516.45 - 72000 = Rs. 15516.45

Answer 2

Answer:

87516.45

Step-by-step explanation:

p=72000

t=1

r=20%

=(72000x105x105x105x105)÷(100x100x100x100)
