In a school, students using school bus, bike and bicycle for transport are in the proportion 6 : 3 : 1. If the total strength of the school is 1200, find the number of students who use bicycle for transport. (Each student uses only one of the given 3 modes of transport)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 120.
The ratio of students using school bus, bike, and bicycle = 6 : 3 : 1
The total strength of the school = 1200
Total Students = Ratio × Number of students using any one vehicle
Let the number of students using the school bus, bike, and bicycle be 6x, 3x, and x respectively.
⇒ 6x + 3x + x = 1200
⇒ 10x = 1200
⇒ x = 120
Number of students who use bicycles for transport = x = 120
