Question

the sum of the digit of a two digit number is 9 the number is 6 times the unit digit find the number​

Answer 1

Let the digits be x and y

x + y = 9 . ... 1

The number is 10x + y

y is the unit digit

So, 10x + y =6y

10x=6y-y

10x = 5y

y=2x ... 2

From eqn 1 and 2

x + 2x = 9

3x = 9

then, x = 3

And y =6

The number is 36 (10x+y)
