Substituting the value of x = 3y in equation (i), we get Therefore, we have 10y + x + 36 = 10x + y If 36 is added to the number, digits interchange their places, The number obtained by reversing the digits is 10x + y.
If 36 is added to the number, the digits interchange their place. The units digit is thrice the tens digit. Substituting the value x in equation (i), we getĢ. Solution:Īdding equation (i) and (ii), we get 2x = 16 The sum of two number is 14 and their difference is 2.
