Answer:
64
Step-by-step explanation:
Let the original number be 10x + y
The new number is 10y + x
ATP,
10x + y + 10y + x = 110
= > 11x + 11y = 110
= > 11(x+y) = 110
= > (x+y) = 10 -------- (1)
10x + y - 10 = 5 (x+y) + 4
Substituting x + y in the equation
10x+y - 10 = 5x 10 + 4
10x + y -10 = 54
10x+y = 64
The original number is 64
