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)
Answer & explanation
Correct answer: option 1
Bus : Bike : Bicycle
No. of students 6 : 3 : 1
Total = 10r =1200
r = 120
No. of students using bicycles = r = 120
Alternate method,
No. of students using bicycle as mode of transport = $\frac{1}{10}$ x Total no. of students = $\frac{1}{10}$ x 1200 = 120
