Study the following information carefully and answer the given questions. Data below represent number of people required for various project to be completed in various days :

If in Team P, total number of workers `= 0.5Z xx 2M,` then what is the number of days required by Team P to complete Project C?

Options

A. 75 days
B. 60 days
C. 90 days
D. 80 days

Answer

C

Explanation

Work unit of project C in both situation 1 and situation 2 are same ,br> `rArr Z^(2) xx 75 = M^(2) xx 108`
`rArr (Z^(2))/(M^(2)) = (108)/(75) = (36)/(25)=(6^(2))/(5^(2))`
`rArr (Z)/(M) = (6)/(5)`
Total unit work of project ` C = 36 xx 75 = 2700`
Days required by Team P to complete
Project `C = (2700)/((0.5Z xx 2M))= (2700)/(30) = 90` days
