Question

The sum of the digits of a two-digit number is 9. The number is 6 times the units digits. Find the number ​

Answer 1

Let the digits be x and y,

so the number is 10x+y

Given,

1) x+y=9

2)10x+y=6y

  10x=5y

  x=y/2

substituting x value in eqn 1,

y/2+y=9

(3/2)y=9

y=9*2/3=6

x=9-6=3

hence the number is 36
