Let the tens and unit digit of number are =x,y respectively
If the digits are reversed then the number is 10y+x.
⇒10x+y=4x+4y
⇒10x+y−4x−4y=0
⇒3(2x−y)=0
⇒2x−y=0
⇒2x=y------(1)
⇒10x+y+18−10y−x=0
and y=2x=2(2)=4
A two digit number is such that the sum of its digits is 4. If 18 is added to the number, it's digits are reversed. Find the number.
A two digit number is 3 more than 4 times the sum of its digits if 18 is added to the number its digits are reversed find the number
