A student has 5 subjects in an examination. The distribution of hard work of 16 hours a day over 5 subjects and marks obtained 400 out of 500 are shown in the charts.
How much time did the student spend on Math and how much marks were obtained in math?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6.4 hrs and 84 marks
Total time of hard work in a day = 16 hours
Time spent on Math = (40/100) × 16 = 6.4 hrs
Marks obtained by the student = 400
Marks obtained in math = (21/100) × 400 = 84
Therefore, the student spent 6.4 hrs on Math and 84 marks obtained in Math.
