Question

The sum of a two digit number and the number obtained by reversing its digit is 121 find the number if its unit place digit is 5

Answer 1

Answer:

Let the digits be x and y

Then number is 10x+y

The number after reversing the digits 10y+x

10x+y + 10y+x =121

11x+11y=121

x+y=11

Since units place digit is 5, 10th place digit = 6

The number is 6×10+5=65 Ans
