Question

The product of five rational numbers is positive. At most, of these rational numbers can be negativeA.1B.2C.4D.5

Answer 1

If we have 5 numbers, to make the product positive, we need more number of positive numbers or an even amount of negative integer. That means there must be two or four negative integers, as the product of two negative umbers is positive. So at the most 4 numbers should be negative.
