Answer 1

Concept : 1 Mark
Pairs : 0.5 Mark each

Here, it's given that 'a' is a positive integer and 'b' is a negative integer and the product is positive integer. So, the value of 'b' must be negative as multiplication of two negative integers will give a positive integer.

(a , b ) = {(1, (-1)), (1, (-2)), (2, (-1)), (2, (-2)), (3, (-1)), (4, (-5))}
