. A two digit number is 27 more than the number obtained by reversing it’s digits. Representthe above situation as linear equation in two variables, with, x and y representing digit atunit’s and ten’s place respectively

The sum of two-digit number and the number obtained by reversing the order of its digitsis 88. Express this information in linear equation in two variables.

A number consist of two digits whose sum is 15. If 9 is added to the number, then the digits change their places. Then the equations formed are x + y = 15 ; x – y = 9x – y = 15 ; x + y = 1x + y = 15 ; 9x – 9y = –9x + y = 15 ; x – y = –9

A two digits number is equal to 7 times the sum of its digits and 21 times the difference of its digits. If xy represents the required number then the simultaneous equations are written as: A) 7y – xy = 7x and 21x + xy = 21 B) 7x + xy = 7y and 21 x – xy = 21y C) 7x – xy = 7y and 21x – xy = 21 D) 7x – xy = -7y and 21y + xy = 21x

The sum of the digits of a two-digit number is 9. If 27 is addedto it, the digits of the number get reversed. The number is

The digits of a two-digit number are in the ratio of 2 : 3 and the number obtained by interchanging the digits is bigger than the original number by 27.What is the original number?
