Question

What sum will amount to ₹18522 in 1.5 years at 10%pa compounded half yearly?

Answer 1

Answer:

₹16000

Step-by-step explanation:

Principal=X

Amount (A)= 18522

Time = 1.5 yrs

Rate (R) = 10% p.a.

Now,

A = P(1 + r/200)^2t

18522 = X (1 + 10/200)^ 2*1.5

18522 = X (1.05)^3

18522= X(1.157625)

X = 18522/1.157625

X = ₹16000

Therefore principal is ₹16000.

Hope it helps you.
