Question

the sum of the digits of a two digit number is 9 the number is 6 times the units digit find the number

Answer 1

Answer:

36

Step-by-step explanation:

let say number = 10x +y

x +y =9

10x +y = 6y

10x = 5y

y = 2x

x + 2x =9

3x = 9

x =3

y = 3*2 = 6

number = 36

Answer 2

Ans.

Let unit digit is 'x',

So, tens digit will be 9-x

So,the number will 10×(9-x)

As per question,

10×(9-x)+x=6x

=>90-10x+x=6x

=>90=6x+9x

=>15x=90

=>x=90÷15

÷>x=6

So, unit digit will 6

So, tens digit will 9-6=3

So, the Number will 36
