Explanation:

Physics Chemistry

Failed 35% 45%

Passed 65% 55%

Passed in both = 22% of total student

percentage of students who are passed in any of the physics or chemistry or both =(65+55) - 22 = 98%

So, the percentage of students who are failed in both = 2%

Therefore, total failed (in both subjects) students = 12

Q:

A) 60 | B) 52 |

C) 45 | D) 35 |

Answer & Explanation
Answer: D) 35

Explanation:

Explanation:

Let the total applicants be 100

Then, 20% got 85 marks

i.e 20 85 = 1700

and 25% got 95 marks

i.e 25 95 = 2375

Now, the remaining applicants are 55 and let the average marks scored by them be x.

2375 + 1700 + 55 x = 60 100

6000 - 4075 = 55x

55x=1925

x=

x=35.
