Answer:
The number is 24
Step-by-step explanation:
Let x and y be the 2 digits .
Note that because x and y are integers and the original number is a multiple of 3 and 4, it must also be a multiple of 12.
So by trial and error:-
Let the number be 12:-
x + y = 3 and 4 * 3 = 12 so this fits the first condition.
x * y = 2 and 3 * 2 = 6 . This does not fit.
Let the number be 24:-
xy =24 , x + y = 6 and 4*6 = 24 . This fits.
x*y = 8 and x*y = 24 This fits.
The answer is 24
