What is the difference between the number of mobile phones sold by A and C together on Monday and that sold by D and E together on Wednesday?

A120

B100 ✓ Correct

C160

D40

Correct answer: (B) 100

Explanation

The answer is 100.

On Monday A sold 80 and C sold 160, together 240.

On Wednesday D sold 24 and E sold 116, together 140.

So the difference is 240 minus 140.

That equals 100.

The other options do not match this value.

So the answer is 100.
