A sum of money becomes 3 times in 5 years at simple interest. In how many year will the same sum become 6 times at the same rate of simple interest? (

A) 10 years
B) 12 years
C) 12.5 years
D) 10.5 years

Correct Answer:



C) 12.5 years

Description for Correct answer:
According to question

\( \Large 2P = \frac{P \times 2 \times 5}{100} \)

R = 40%

At the same rate and Now, same sum becomes 6 times in t years

\( \Large 5p = \frac{P \times 40 \times t}{100} \)

\( \Large t = \frac{500}{40} Years\)

\( \Large t = \frac{25}{2} Years\)

t = 12.5 Years

Option (C)is correct.
