Question

A sum of money at simple interest doubles itself in 8 years 4 month

Answer 1

Answer:

Amount = Principal + Interest

Let P = 100

Then A=200

so

200=100+ (100*r* 25 )/3*100

(100*300)/25*100=R

12%= R

The amount will triple in

300= 100 + (100*12*T)/100

(200*100) /100*12=T

16 years 8 months = T
