Question

Determine the number of students who failed in English and Science but not Maths.

• A. 4
• B. 7
• C. 5
• D. 6
• E. 8

Answer 1

The correct option is D 6

No. of students who failed only in Maths= 20 (Given)

According to condition given,

Students who failed in Maths and English only + Students who failed in Science and Maths only + Students who failed in all three papers= 30-20= 10.

Therefore, 6+8-x=10 (x being the number of students who failed in all three subjects)

Solving the above equation gives x=4

Student who failed in:-

All three subjects=4

Maths and English only=2

Maths and Science only=4

Science and English only=6

English only=16

Science only=18

Hence answer option D
