Is the product of x and y greater than 60?

1. The sum of x and y is greater than 60.
2. Each of the variables is greater than 2.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

1. Insufficient [59.5 and 0.75 ; 40 and 3]
2. Insufficient [3,3 and 21 and 3]

Combined
Sufficient product of xy will always be greater than 60
