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 question says which of the given option (I or II or III) can be left. In this question any two (I or II or III) can be used to answer the given question, hence, the answer is D.

Since any of the two statements are enough to solve the question the other one will be redundant providing same results. So for any combination one of them will be redundant.

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.

How is it possible to find expected answer from only II condition? there is nothing mention about women in IInd condition please explain!

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

I think option A is correct because in other two option they have not mentioned the total day required to complete whole work.

Correct read the question carefully, they're asking the redundant statement and not the required statements.

Any explanations to this? I am also unable to understand. I felt I & II can give the answer.
