Question

The sum of the digits of a two-digit number is 12. if the digits are reversed, the new number is 12 less than twice the original number. Find the original number.​

Answer 1

Step-by-step explanation:

Let the two digit number be 10x+y

Sum of digit : x+y=12 __(i)

A.t.Q : 2(10x+y)−(10y+x)=12

⇒20x+2y−10y−x=12

⇒19x−8y=12

⇒19x−8y−12=0 __(ii)

Put eq. (i) in eq. (ii)

⇒19(12−y)−8y−12=0

⇒228−19y−8y−12=0

⇒27y=216

⇒y=8

x+y=12

x=12−8

x=4

Number : 48
