in the compound interest after 12 years if the
i. yearly
ii. half yearly​

Answer 1

Answer:

Rs 52.5

Step-by-step explanation:

P = 20000

R = 10 % per annum

= 5 % 6 monthly

Compound interest in 1.5 years if compounded 6 monthly

1.5 years = 3 * (6 months) , R = 5 %

Interest = 20000 (1 + 5/100)³ - 20000

= 3,152.5 Rs

if Compounded Annualy

interest for 1 st year

= 20000 * 10 * 1/100

= 2000

Now Amount become = 20000 + 2000 = 22000

Interest for next 6 months = 22000 * 10 * (1/2) / 100 = 1100

Interest = 2000 + 1100 = 3100 Rs

Difference = 3152.5 - 3100 = Rs 52.5

Answer 2

Answer:

Rs 52.5

Explanation:

P=20000

R=10% per annum

= 5% 6 monthly

1.5 years = 3*6 months

R= 5%

20000*10*1/100

=2000

Now Amount became

=20000+2000

=22000

In for next 6 months

22000*10*1/2/100

=1100

Interest= 2000+1100

= Rs 3100

Difference= 3152.5- 3100

= Rs 52.5
