Answer 1

This is a question on ratio and proportions :

30 clerks can handle 90 customers in 3 days.

How many clerks can handle 188 customers in 4 days.

We can represent this information as follows :

30 : 90 : 3

? : 188 : 4

If the customers increase the clerks also increase therefore we take the larger fraction of the customers as follows :

188/90

If the number of clerks increase, we expect the number of days to increase and therefore we take the smaller ratio of the number of days as follows :

3/4

We now multiply the relationship as follows :

3/4 × 188/90 × 30 = 47

= 47 clerks
