If the simple interest for 5 yr be equal to 40% of the principle, it will be equal to the principle after?
Correct Answer: 12 yr 6 months
Explanation:
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
