C) 16
D) 18
Correct Answer: B
Solution :
Given, number of students in each subject are |
Hindi = 60, English = 84, |
Mathematics = 108. |
The prime factors of each subject students are |
\[60=2\times 2\times 3\times 5={{2}^{2}}\times 3\times 5\] |
\[84=2\times 2\times 3\times 7={{2}^{2}}\times 3\times 7\]\[108=2\times 2\times 3\times 3\times 3={{2}^{2}}\times {{3}^{3}}\] |
The maximum number of participants that can accommodated in each room |
= HCF (60, 84, 108) |
= Product of the smallest power of each common prime factor involved in the numbers |
\[={{2}^{2}}\times 3=12\] |
