# What will be the Sum? If

A Sum of Money at Simple Interest Amounts to Rs.815 in 3 Years and to Rs.854 in 4 years. What is the Sum?

- Rs.420
- Rs.698
- Rs.768
- Rs.812

**Answer: (2) Rs.698
Explanation:-**

The amount of 3 years = 815 and the amount of four year = 854

then, SI for one year = 854 – 815 = Rs.39

SI for three years = 39 x 3 = Rs.117

Principal = 815 – 117 = Rs.698

Hence, the sum of money is Rs.698
