Answers
Answer:
Given : 312, 260 and 156 students in class X, XI and XII respectively. Buses are to be hired to take these students to a picnic.
To Find : the maximum number of students who can sit in a bus if each bus takes equal number of students
Solution:
Assuming in any bus only on class students sit
We need to find HCF of students of class X, XI and XII
312=2*2*2*3*13
260 = 2 * 2 * 5*13
156 = 2 * 2 * 2 *13
HCF = 2 * 2*13 = 52
52 Students can sit in a bus
Number of buses required = 312/52 + 260/52 +156/52
=6 +5 +3
=14
Maximum 52 Students can sit in a bus
14 number of buses required
