Question

the digits of a two digit number differ by 3. if the digits are are interchanged and the resulting number is added to the the original number we get 143. what is the original number?​

Answer 1

equation....1

let the numbers of two digit number be

1.x

2.x-3

ATQ....

10*x+(x-3)+10*(x-3)+x=143

10x+x-3+10x-30+x=143

11x+10x+x-3-30=143

22x-33=143

22x=143+33

x=176÷22

x=8

so,the original number =8-3=5

85

check

85+58=143
