Step-by-step explanation:

Answer 2

Answer:36

Step-by-step explanation:

Let the digits be x and (x-3).

Therefore, the number is

10(x-3)+x

10x-30+x

11x-30

Reversed number is

10x+(x-3)

11x-3

A.T.Q

7(11x-30)=4(11x-3)

77x-210=44x-12

77x-44x=210-12

33x=198

x=198/33

x=6

Number =10(6-3)+6

=30+6

=36
