Question : Different choices made by a group of 200 students are given below in percentage. The number of students who have taken neither Science nor Commerce is:
| Percentage of students in different streams | |
| Name of streams | Intake Ratio |
| Science | 29% |
| Arts | 29% |
| Commerce | 31% |
| Home Science | 6% |
| Others | 5% |
Option 1: 80
Option 2: 120
Option 3: 60
Option 4: 40
Correct Answer: 80
Solution :
According to the given table, we have:
Total number of students = 200
Percentage of students in all streams = 100%
Percentage of students who neither have commerce nor science = Percentage of students in Arts, Home science, and Others
= (29 + 6 + 5)% = 40%
$\therefore$ Number of students who neither have commerce nor science = $200\times\frac{40}{100}$ = 80
Hence, the correct answer is 80.
