Question

if the difference of two digit number and the no.obtained by reversing the digits is 36 ,find the difference between the digits of 2 digit no.
​

Answer 1

Answer:

Let the tens place digit be a

And unit place be b

Number = 10a + b

Reversed number = 10b + a

(10a +b) - (10b +a) = 27

=> 10a +b - 10b - a = 27

=> 9a - 9b = 27

=> a - b = 3

Difference of digits = 3
