Question

pls answer this and no spams ​

Answer 1

Step-by-step explanation:

ten's digit is x

and unit digit is y

x is equal to 2y

10x +y is 6

10x +2x =6

12x =6

x=1/2

y is 1/4

number formed is 42 by cross multiplication

Answer 2

Answer:

The number is 42.

Step-by-step explanation:

Let the digit at the ten's place be x and the digit at the one's place be y.

Therefore, the number will be =10x+y.

Now, According to the question,

Ten's digit is twice the unit digit

So, x=2y ------(1)

Also, The sum of the digits is 6.

So, x+y=6 -------(2)

Now, we can substitute the value of x from eq (1) in eq(2).

x+y=6

2y+y=6

3y=6

y=6/3

y=2.

Now from eq(1)

x=2y

x=2×2

x=4.

Now the number is 10x+y.

so, 10x+y =10×4+2 =40+2 =42.

Hence the number is 42.
