  1. If the simple interest for 5 yr be equal to 40% of the principle, it will be equal to the principle after ?
    1. 12 yr 3 months
    2. 12 yr 6 months
    3. 12 yr 4 months
    4. 12 yr 9 months
Correct Option: B

If interest is 40% of the principal then time = 5 years.
So, when interest would be equal to 100% of the principal time would be
= (100/40) x 5 years = 12.5 years
= 12 yr 6 months
