There is 75% increase in an amount in 5 years at simple interest. What will be the compound interest of Rs 40000 after 2 years at the same rate?

75*100/100*5 =Rate of interest 15%=R 40000(1+15/100)^2=c.i 2100=c.i amount = 42100

amount = (175/100)×principal. SI=(75/100)×principal. SI=(principal×5×Rate)/100. Rate=15%. CI=12900
