Question

Sum of two distinct numbers is positive then which of the following statements is correct?

(a) Both numbers are equal and negative

(b) Greater one positive and smaller one negative

(c) Both positive

(d) Both negative

I have been asked this question during an interview.

I need to ask this question from Applications of Linear Equation (Just Solving the Equations) topic in division Linear Equations in One Variable of Mathematics – Class 8

Answer 1

Right choice is (d) Both negative

The best explanation: Here we are given that there are two distinct numbers, so the option stating equal and negative is ruled out. The second information we have is the sum is negative, so if the greater number is positive than the sum is positive and hence the option which states greater one positive and smaller one negative also is ruled out. Now we have two options left they are both positive or negative. We know that sum two positive number is positive. So the option left is both negative which is the correct options.
