Please explain. . . how clearly,I gives the answer ? ? ?

Newbie said:   1 decade ago
Any explanations to this? I am also unable to understand. I felt I & II can give the answer.

From II we can find the no of days required by a eight men to complete i.e if 16 is for 24 then 8 is for 12 days. from option III we can find the relation between the men and woman working days tat is 3:4 , 4/3*12=16 days for 8 women, then for 14 women it is 28 days .. it is clear that option II and III are mandatory to give the answer. then how is option D right??

See the question is which option is redundant right... that means which one of I,II or III can be left

Since pairwise I,II II,III and III,I can give u answer so any of these statements I,II or III can be redundant..

That's y option d) is correct

The answer says "Clearly, I only gives the answer". How is this possible? from I you only get the equation 19m+12w=1/18 With this eq and with the data given in the problem statement, how can you get an answer for this question?

The equations formed contain two unknown variables so any two options are required to find the no. of days..
The options are incorrect

Those who don't bother about paying attention to terms and conditions for usage of a product. Understanding this equation is nearly impossible for them.
