| Total | 917 | 924 | 904 | 919 | 904 | 910 |
The number of students studying in class VII from school U is what percentage of the total number of students from all the classes together from that school (rounded off to 2 digits after decimal)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 17.36%.
Given that
The number of students studying in class VII from school U = 162
The total number of students from all the classes together from school U = 150 + 160 + 162 + 160 + 161 + 140 = 933
According to the question
The required percentage = (162/933) × 100 = 17.36%
