## Aptitude question and answer on Simple interest

**Question :** At a certain rate of simple interest, a certain sum doubles itself in 10 years. If will triple itself in A. 12 years

B. 15 years

C. 20 years

D. 30 years

Answer : C. 20 years

**Explanation:**

Let sum = x.

Then S.I. = x and time = 10 years

\(\dot{..}\) Rate = \(\Bigg( {100 \times x \over x \times 10} \Bigg) \%=10\%\)

Now , Sum = x, S.I.=2x , Rate = 10 %

\(\dot{..}\) Time = \(\Bigg( {100 \times 2x \over x \times 10} \Bigg) \)years

= 20 years
