Answer 2

Answer:

Let, the initial sum of money be "Rs. x."

We have

Time taken to make the sum of money 2x = 12 years.

Since, the sum become 1x in 0 years. So, it will become 1.5x in 6 years.

Therefore, the time taken to make the sum of money 3x is given by $\sf{t_3 = 12\times 1.5=18~ years}$

Thus, the required time is 18 years.
