Question

p = 10000 , R = 6% , T = 18 month ​

Answer 1

Given:-

• Principal,P = Rs. 10000
• Rate,r = 6 %
• Time, n = 18 months

To find out:-

Find half yearly compound interest .

Solution:-

If the interest is payable half-yearly, then r we take r/2 and for n we taken 2n.

★ Rate,r = 6 % = 6/2 = 3 %

★ Time, n = 18 months = 1 ½ years = 3/2 × 2 =3 years

We know that,

A = P ( 1 + r/100 )^n

A = 10000 ( 1 + 3/100 )³

A = 10000 ( 100 + 3 / 100 )³

A = 10000 ( 103/100 )³

A = 10000 × 103/100 × 103/100 × 103/100

A = 1,092,727 / 100

A = 10,927.27

Now,

Compound interest = Amount - Principal

= 10,927.27 - 10,000

= 927.27
