1.

if the difference of two digit number and the number obtained by reversing the digits is 27 find the difference between the digits of the 2 digit number

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
