|How 2 & 3 give the answer? Could you please explain me?|

|1 men's 1 day work = 1/10*6 = 1/60.
(10 men + 10 women)'s 1 day work = 7/24.
1/10*6*10 + 10 women = 7/4.
So 10 women's 1 day work = 7/4-1/6 = 3/24 = 1/8.

|By using 1st option how we can solve the problem?|
|Simar said: (Aug 22, 2016)|
In your answer to solve 2&3, you are using 1 men's 1-day work = 1/60.
I think this is derived from statement 1. Other statements are not mentioning this. So why this used here in solution?

|A contractor estimates that he will employ 20 men to build a tank and complete works in 10 days. After working 3 days together 5 men return back. How many days more will the remaining men take to complete work.
Please help me to answer this.

20 men, 1 day work = 1/10.
20 men, 3 day work = 3/10.
Remaining work = 1 - 3/10 = 7/10.
Now we take 1 men, 1 day work = 1/60,
Now 5 men return back therefore only 15 men will present.
Now 15 men, 1 day work = 15/200.
Therefore to complete remaining 7/10 work number of days are = (7/10) * (200/15) = 28/3 days.

In the question, they asked 10 women can finish the work in how many days?
1st option it gives only about the men na. How come women days can be obtained?

|I think the 1st statement must be used. Along with 1st statement, you can use either statement 2 or statement 3 to get the answer. So, in this case, answer should be E.|
