Kindly solve this work question - Page 3

@RMKamran Thanks a lot for help, I'm also preparing it and I was sort of rattled to have not come across it yet. I looked properly in the contents and I found it. I'm using GRE books.

You are right HCC books will not work, they will be good to brush up the basics but General Ability tests are a lot more trickier.

P.S: You ask as much questions as me, I'm reducing my brother to tears these days by asking a zillion questions.

Good to know that I'm not the only one :P

Count yourself amongst the luckiest ones because your brother helps you in these questions. I have no one to get assistance. GRE is also fine but the one I have told i.e., 'Caravan aptitude book' is pretty good. You should buy that as well.There are 746 questions in it that you can practice.

Stay blessed.

having a test tomorrow?

With the word used OR the problem is quite easy to solve as we have three equations and three unknown. But if there would have been word AND instead of OR then how would answer be 7.5? If we suppose the word used in the problem is AND then we will have three unknown with two equations that is impossible to solve.
Kindly post the method of solution.

Then, 6 men + 8 boys = 6 + 4 men = 10 men
work done = 3 men × 20days
That is, 3 × 20 = 10 × (required days)
3 × 2 = 1 × (required days)
so (required days) =6.

I think, of all the solutions posted above, this is the correct one.

Now come to the 'then' part.

because
6 men = 12 boys

therefore,

6 men + 8 boys = 12 boys + 8 boys = 20 boys

Now days required to complete the task = 120 boy-days /20 boys = 6 days

120 days are required by one boy to complete the task so the days required by 20 boys will be 120/20 = 6 days.

You can also solve by pursuing with the men instead of boys, i.e. 1 man = 2 boys.

simple and fast way:

6/20 = x/20
6=x
