reversed. Find the number.​

Answer 1

Answer:According to Me, the ANSWER is 36

Step-by-step explanation:

Let the unit digit be y and tens digit be x

No. Formed = 10x+y

Reversed No.= 10y+x

Eq.1▪ x+y= 9

Eq.2▪ 10y+x=10x+y+27

Solving eq2 we get

9y-9x=27

Eq.3▪y-x=3

On solving eq1 and eq3 we get

x=3 y=6

Original Number is 36
