Detailed Solution

Given that a sum of money at simple interest amounts to Rs. 815 in 3 years and to Rs. 854 in 4 years.
Amount after 4 years = Amount after 3 years + Simple interest in 1 year

Simple interest in one year = Amount in 1 year - Principal

∴ Simple interest in one year = Rs . (854 - 815)

\Rightarrow Simple interest in one year = Rs . 39

So,

Simple interest for 3 years = 39 \times 3

\Rightarrow Simple interest for 3 years = Rs . 117

We know,

Sum = Amount - Interest

\Rightarrow Sum = Rs . (815 - 117)

\Rightarrow Sum = Rs . 698

Thus, the sum is Rs. 698.
Therefore, the correct option is 1.
