Question

3. The digit in the tens place of a 2-digit number is three more than the digit in the units place. The number is __________________

Answer 1

Let the two numbers be x and y

x = 3y ( given )

( 10x + y ) + ( 10y + x ) = 88 (given )

11x + 11y = 88

x + y = 8

Implies, 3y + y = 8

y = 2 and x = 6
