Aptitude - Time and Work - Discussion
Each of these questions is followed by three statements. You have to study the question and all the three statements given to decide whether any information provided in the statement(s) is redundant and can be dispensed with while answering the given question.
8 men and 14 women are working together in a field. After working for 3 days, 5 men and 8 women leave the work. How many more days will be required to complete the work? | |
I. | 19 men and 12 women together can complete the work in 18 days. |
II. | 16 men can complete two-third of the work in 16 days. |
III. | In 1 day, the work done by three men in equal to the work done by four women. |
Clearly, I only gives the answer.
Similarly, II only gives the answer.
And, III only gives the answer.
Correct answer is (D).
i.e. When we find answer using I and II; III is of no use means III is redundant i.e. we can dispense it.
Similarly, there are two more cases in which we can dispense I and II also I. We can dispense I or II or III.
However there is no such option of (I) or (III) could you please correct this in the question?
Please feel free to reply here if any of this does not make sense or if you find me to be wrong. I'd like to learn.
The option D is absolutely right.
