Question

. In a seminar, the number of participants in English, Mathematics and Science are 36, 60 and 84 respectively. Find the minimum number of rooms required if in each room the same number of participants are to be seated and all of them being in the same subject.
A) 10
B) 15
C) 20
D) 8

Answer 1

Answer:

Hence, we have found our common divisor to be 12, we therefore are going to divide this by the number of the students, to get how many rooms are needed. 84 + 60 + 108 =252. Hence 21 rooms are needed.
