The number obtained by interchanging the digits of a two-digit number is less than the original number by 36. The sum of the digits of the number is 8. What is the original number ? Choose the correct choice:
A) 71
B) 62
C) 53
D) 35
E) 45
Explanation :   Let the number be 10x + y.   ∴ x + y = 8 .....(i)   10x + y - (10y + x) = 36 ∴ 9(x - y) = 3   ∴ x - y = 4 .......(ii)   From equation (i) and (ii): x = 6, y = 2   ∴ Number = 62   Answer : Option 62
