Question

a sum of money lent out at simple interest Doubles itself in 8 years find in how many years will the sum become three times of itself at 12.5%

Answer 1

Answer:

Time = 16 years

Step-by-step explanation:

let P = x

so SI = A - P = 3x - x = 2x

now T = SI*100/(P*R)

           = 2x*100/(x*12.5)

           = 2*2*100/25

       T   = 16 years
