Answer :
42 times 10
210 times 2
210 + 210
70 times 6
60 tmes 7
140 times 3
and etc
210 times 2
210 + 210
70 times 6
60 tmes 7
140 times 3
and etc
If we do it algebraically, we get
x + y = 420
This is the simplest equation. You see now this is a linear pair in two variables. Thus, there will be infinitely many solutions.
E.g - 419 + 1 = 420
42 * 10 = 420
21 * 20 = 420
etc,....
