Question

In a class, 200 student offer mathematics and physics or both, if 120 offer mathematics and 100 offer physics, how many student offer both mathematics and physics?

Answer 1

Hey mate...☺☺

Here is ur ans...✌✌

Students for mathsmatics and physics = 200

Only mathematics = 120

Only physics = 100

Total physics and mathematics = 120+100= 220

So students offering both = 220-200= 20

So there r only 20 students who offer both.

Hope it helps u...❤❤❤

Thanks...✌✌✌
