Answer 2

T. o

X+3. X

Let the unit digit be X

Tens digit be X+3

10(X+3)X

digits are interchanged = 10x+X+3

$10(x + 3) + x + 10x + x + 3 = 143 \\ = > 10x + 30 + 12x + 3 = 143 \\ = > 22x + 33 = 143 \\ = > 22x = 143 - 33 \\ = > 22x = 110 \\ = > x = \frac{110}{22} \\ = > x = 5$

x = one's place = 5

ten's place = x+3

ten's. one's

x+3.

5+3

8. 5

original number = 85
