Divide 60 by half and deduct twenty. What do you get?

A 120

B 100

C 60

D 30

Correct Answer: Option B

The twist is that, the question specifically asks you to divide the number by half (1/2), not by two (2).

Thus, dividing 60 by half means,

60 / (1/2) = 60*2/1 = 120

And deducting 20 from the derived value = 120 - 20 = 100
