If M and N represent the number of analysts and the number of testers recruited during the years 2017 to 2021, then M minus N equals

D44 ✓ Correct

Correct answer: (D) 44

Explanation

The answer is 44.

Analysts recruited from 2017 to 2021 total 136 plus 120 plus 118 plus 128 plus 144, which is 646.

Testers recruited over the same years total 100 plus 112 plus 124 plus 136 plus 130, which is 602.

So M is 646 and N is 602.

The difference M minus N is 646 minus 602.

That is 44.

So the answer is 44.
