At a pet store 4 goldfish are selected at random from each group of 50. At this rate, how many goldfish will be selected in total if the pet store has 2000 goldfish?

A)  4

B) 160

C) 200

D) 2000


Choice B is correct.

Since, 4 goldfish are selected from a group of 50.

Therefore, the number of goldfish that will be selected out of 2000 goldfish will be,

(4/50) * 2000 = 160.
