**Answer:**

The difference between the compound interest and simple interest on a certain sum at 10% per annum for 2 years is Rs. 631. Find the sum. ( x / 100 ) = 632 * x = 63100.

**Step-by-step explanation:**

Let the sum be Rs. x. Then,

C.I. = x ( 1 + ( 10 /100 ))^2 - x = 21x / 100 ,

S.I. = (( x * 10 * 2) / 100) = x / 5

(C.I) - (S.I) = ((21x / 100 ) - (x / 5 )) = x / 100

( x / 100 ) = 632 * x = 63100.

Hence, the sum is Rs.63,100.
