SSC CGL 2025 PYQ — Question 12

Let the principal amount = P

In 10 years, the amount becomes 3P, i.e., interest = 2P

So, interest for 10 years = 2P

In simple interest, interest is proportional to time.

The amount to become 5 times = 5P

I.e., interest = 4P

$\frac{4P}{2P} = \frac{T}{10}$

T=20 years

Answer: 20 years
