Question

the difference between a number of three digit a, b, c and the number obtained by reversing the digits is 198 find the difference of a and c

Answer 1

since the number is 3 digit 1 will be on 100s place b will be on tens and c will be on units place

and when reversed c will be on 100s b will be on tens his usual position and a will be on units place

So, 100a + 10b + c - 100c - 10b - a = 198

99a - 99c = 198

99(a - c) = 198

a - c = 198/99

a - c = 2
