Question

find the compound interest on ₹ 12 at 12.5 percent in one year compounded half yearly​

Answer 1

Solution:

Given that,

Principal amount = 256

Rate of Interest = 12.5 %

Number of years = 1

The formula for amount when compounded half-yearly is:

A = P (1 + R/2/100) ²t

Where,

P is the principal amount

A is the total amount

R is the rate of interest

T is the number of years

Plugging in values, we get

A = 256 (1+12.5/2 x 100) ² x 1

On solving we get,

A = 256 (212.5/200)²

=  256 x 1.12890625

= 289

Hence the total amount is Rs 289.
