B) 12
C) 15
D) 18
E) 21

Answer :

Answer:

option (d)

Explanation:

Given,

1 ton of a particular item can be stack in= 3 man-hours

36 ton of a particular item can be stack in=  36 x 3 man-hours

                                                                     = 108man- hours

Number of hours = 6 hours

Number of people = [tex]\frac{108 \text{man-hours}}{6}[/tex]

                               = 18

Hence, the number of people required is 18.

Therefore, option (d) is correct.
