Question

1.
The four directors of a certain company
supervised a certain number of employees each. If
the ratio of employees supervised by the directors
is 3:5:7:8, which of the following CANNOT be
the total number of employees supervised?
(A) 115
(B) 92
(C) 74
(D) 69
(E) 46​

Answer 1

⊕ANSWER⊕

The total of the ratio is 3 + 5 + 7 + 8 = 23  

So, the number of employees is a multiple of 23  

115 = 23 x 5  

92 = 23 x 4  

69 = 23 x 3  

46 = 23 x 2  

74 is not divisible by 23...i.e. total employees cannot be 74
