Question

There are $156,208and260$ students in groups A, B, and C, respectively. Buses are to be hired to take them for a field trip. Find the minimum number of buses to be hired, if the same number of students should be accommodated in each bus.

Answer 1

Since , the same number of students are to be distributed in groups

we need to find the HCF of number of students in different groups

$HCF(156,208,260)=52$

Hence, 52 students can accommodate in each bus

So, Total number of Buses $=\frac{TotalStudents}{52}=\frac{624}{52}=12$
