Question

If the amount will be doubled in 6 year then in how many year amount will be 3 times​

Answer 1

Answer:

9 years

Step-by-step explanation:

Let initial amount = x

After 6 years, amount = 2x

=> After 6*1.5 years, amount = 2*1.5x = 3x

=> 6*1.5 is nothing but 9. So in 9 years amount will become thrice that of original amount.
