Study the following table and answer the questions.

Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.

Subject Marks out of 50
40 and above 30 and above 20 and above 10 and above 0 and above
Physics9328092100
Chemistry4216681100

2.
If at least 60% marks in Physics are required for pursuing higher studies in Physics, how many students will be eligible to pursue higher studies in Physics?
27
32
34
41
Answer: Option
Explanation:

We have 60% of 50 = ( 60 x 50 ) = 30.
100

Therefore Required number

      = No. of students scoring 30 and above marks in Physics

      = 32

The answer should come 41.
Since 'atleast 60%' means to include the student who scored more then 30 marks,
Which we have 32 stds. Who scored in thirty and 9 stds who scored in fourth,

So, 32 + 9 = 41.

Note: At least, 30 marks means; (greater than 30), which is inclusive of all students who scored from 30 to 50.

Friends, 32 is correct answer. It's sum of 40 and 30. See below calculation:

40 and above: 9 - 0 = 9
30 and above: 32 - 9 = 23
20 and above: 80 - 32 = 48
10 and above: 92 - 80 = 12
0 and above: 100 - 92 = 8

Total Student = (9 + 23 + 48 + 12 + 8) = 100 student.

So, 32 is a sum of 40 and 30 (and above) students who got at least 60% marks in Physics.

(0 - 9)-8; (10 - 19)-12; (20 - 29)-48 - (30 - 39)-23; (40 - 50)-9.
The question says at least 60%, here 60% mark is 30.
30 and above marks column mentioned 23 + 9 = 32 students.

So the answer 'option B'.

Look as the accumulative frequency, as a total number of students is 100. So it adds one over the other then the answer is 32.

It may be 32+9=41.

Because at least 60%.

32 is right answer because it ask at least 30 n above here 30 is also included in 40 and above 30 not included.

I think it must be 41.
