Q. A number consists of two digits whose sum is

9

27

is added to the number, its digits are interchanged. Are the given steps to find the number true?
Step

1

: Let the unit's digit be x
Step

2

: Then, ten's digit

= (9 - x)

∴

= 10 \times (9 - x) + x \Rightarrow 90 - 10 x + x = (90 - 9 x)

3

27

90 - 9 x

117 - 9 x

4

: Number with digits interchanged is

10 x + (9 - x) = 9 x + 9

5

117 - 9 x = 9 x + 9

6

: Therefore unit's digit

= 6

and ten's digit

= 3

7

: Hence the number

= 36

.
