Question

If the simple interest on a sum at 4% per annum for 2 years is ruppes 80 then the compound interest on the same period is​

Answer 1

Answer:

Step-by-step explanation:

We have to find the principal amount.

Interest for 13 months at 4%

Interest per year = 4 %

interest per month = 4 ÷ 12 = 1/3 %

Interest for 13 months = 1/3 x 13 = 13/3 %

Interest for 8 months at 6%:

interest per year = 6 %

interest per month = 6 ÷ 12 = 0.5 %

interest for 8 months = 0.5 x 8 = 4 %

Let the principal amount be x

13/3% of x – 4% of x = 40

1/3 % of x = 40

1% of x = 120

100% of x = 120 x 100 = Rs 12000

Answer 2

Answer:

p*15/100*4=1920

60 p =1920*100 =192000.00

p =192000/60=3200.00

compound interest

3200*30/100*1 =960.00

(3200+960=4160.00)

4160*30/100*1 =1248.00

5408–3200=2208.00

compound interest =2208.00
