Question

. A two-digit number is such that the sum of the ones digit and the tens digit is 10. If
the digits are reversed, the number formed exceeds the original number by 54. Find
the number

Answer 1

Answer:

28

Step-by-step explanation:

Let the first digit = "x"

Let the second digit = "10-x"

1st eqn. = 10x + 10 - x + 54 = 100 - 10x + x

Now,

9x = 36-9x

18x = 36

x = 2

number = 10*2 + 10 - 2 = 28

reversed = 82
