In a library system with 6 branches, 60 workers are employed. If no library has fewer than 7 workers and no more than 11, what is the minimum number of workers in any 2 of the branches?

A 10
B 14
C 16
D 19

Correct Answer: 16

Maximum number of workers possible to remain in any 4 branches = 4×11 = 44 Workers remaining = 60 - 44 = 16 which can be divided between the two remaining branches in such a way that there is no fewer than 7 workers in any of the two branches. So, minimum 16 workers can remain in any 2 branches.
