Question:
A 2-digit no.is such that the ones digit is 1more than the tens digit. The ratio of this no.and the no.formed by reversing it
Answer:
Let the tens digit of the number is x
So, unit digit of the number is x + 1
Now, the number is 10 * x + x + 1 = 11x + 1
After reversing the digit of the number, we get new number = 10(x + 1) + x
= 10x + 10 + x
= 11x + 10
Now, ratio = (11x + 1) : (11x + 10)
