The percentage of the number of students in activity II to that of activity IV is: (consider up to two decimals)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 35.48 percent.
Given that
The number of students in activity II = 50 + 150 + 150 + 50 + 50 + 50 + 50 = 550
The number of students in activity IV = 250 + 125 + 350 + 275 + 250 + 150 +150 = 1550
Hence, The required percentage = (550/1550) × 100 = 35.48 %
