SI for 2 years=40

THUS,SI for 1 year=40/2=20

As for the first year CI and SI are always same so,

CI for first year=20

give that CI for 2 years is 41;

So CI for second year =41-20=21

Difference in CI for two successive years=21-20=1


1 is the interest for one year on the interest of first year,that is,on rupees 20;

therefore; the rate is 5% per annum.
