- At what subject the student is sharp?

(a) English (b) Mathematics (c) Science (d) History - In which subject the student is poor?

(a) English (b) Mathematics (c) Science (d) History - What are the average marks obtained by the student?

(a) 57 (b) 63 (c) 80 (d) 48 - What is the average percentage obtained by the student?

(a) 80% (b) 63% (c) 57% (d) 90% - What is the ratio of the highest marks to the lowest marks obtained by the student?

(a) 2:11 (b) 9:2 (c) 2:9 (d) 11:2

**Answer: (b) Mathematics****Explanation:-**

The student is sharp in mathematics subject .Hence, the correct answer is option (b) Mathematics.

**Answer: (d) History****Explanation:-**

The student is poor in history subject.Hence, the correct answer is option (d) History.

**Answer: (a) 57****Explanation:-**

Total marks obtained by the students = 55 + 90 + 40 + 80 + 20

= 285

Then, the average marks obtained by the students = 285/5

= 57Hence, the correct answer is option (a) 57.

**Answer: (c) 57%****Explanation:-**

The average percent marks obtained by the student = 285 x 100/500

= 57%Hence, the correct answer is option (c) 57%.

**Answer: (b) 9: 2****Explanation:-**

The highest marks obtained by the student = 90

The minimum marks obtained by the student = 20Then, ratio of the highest mark to the lowest marks obtained by the student = 90/20

= 9: 2Hence, the correct answer is option (b) 9: 2.
