Let us assume sum as 100

Let us assume sum as 100Amount =sum+simple interest

Let us assume sum as 100Amount =sum+simple interestIf amount becomes 400(as 4 times the sum)

Let us assume sum as 100Amount =sum+simple interestIf amount becomes 400(as 4 times the sum)Then simple interest is 300

Let us assume sum as 100Amount =sum+simple interestIf amount becomes 400(as 4 times the sum)Then simple interest is 300By using formula pnr/100

Let us assume sum as 100Amount =sum+simple interestIf amount becomes 400(as 4 times the sum)Then simple interest is 300By using formula pnr/100(100*x*10)/100=300

Let us assume sum as 100Amount =sum+simple interestIf amount becomes 400(as 4 times the sum)Then simple interest is 300By using formula pnr/100(100*x*10)/100=300_X=30 yrs_
