Question

The sum of the digits of a two digit number is 5.If the digits are reversed ,the number is reduced by 27. Which of the following are the equations of the statements( by assuming the unit's digit as x and ten's digit as y) *​

Answer 1

Let the units digit be x.

The tens digit =5−x

Original number =10(5−x)+x=50−9x

If digits are reversed, number is reduced by 27.

50−9x−27=10x+5−x

23−9x=9x+5

18x=18

∴x=1

Tens place =5−1=4

Therefore, the number is 41.
