Of the 60 employees at a bank branch in Indore, 42 attended a morning workshop and 35 attended an afternoon workshop. The bars push the two groups to opposite ends. At least how many employees attended both workshops?

Question

Accepted Answer

17. The two groups cover 42 + 35 = 77 seats but there are only 60 employees, so at least 77 - 60 = 17 must be counted in both. 35 is the most that could attend both, 18 is 60 - 42, and 77 is just the sum.
