Test Preparation on CA/CS Foundation MCQ Question Inequalities

1.

If a > 0 and b < 0, it follows that-

11/a > 1/b
21/a < 1/b
31/a = 1/b
4None of these

since a is a positive number therefore its reciprocal i.e. 1/a will also be positive

since b is a negative number therefore it's reciprocal i.e. 1/b will also be negative

so, we can conclude that 1/a is > 1/b
