Physics | 9 | 32 | 80 | 92 | 100 |
Chemistry | 4 | 21 | 66 | 81 | 100 |
Average (Aggregate) | 7 | 27 | 73 | 87 | 100 |
4.
The number of students scoring less than 40% marks in aggregate is?
Answer: Option

We have 40% of 50 = | ![]() |
40 | x 50 | ![]() |
= 20. |
100 |
Required number
= Number of students scoring less than 20 marks in aggreagate
= 100 - Number of students scoring 20 and above marks in aggregate
= 100 - 73
= 27.

But using less than in the sentence makes it start from 10 and above. Why is the aggregate for 20 and above being used instead?

I think 0 to 100 indicates the total number of students.
Then from that value deduct the 20 and above.
i.e 100-73 = 27.
Then from that value deduct the 20 and above.
i.e 100-73 = 27.

Here, it is clearly mentioned that less than 40%. So, why would we consider 40% and above?
Please, anyone, explain me.

The word less than symbolise less than 20 marks so we need to take 10 and above only. Can you please explain this?

If there is no word lesser then answer will become 73.
If there is lesser than = no.of students -73.
If there is lesser than = no.of students -73.

It is simple, its the total number
ie. 100 - (20 and above) = below 20.
ie. 100 - (20 and above) = below 20.
