A person borrowed a certain sum at the rate of 20% per annum

A group consists of m equally efficient workers. A piece of work was started by one of them. The \(p^th\) worker (where \(2\leq\)p \(\leq m\)) joined the work (p - 1)x days after the \((p-1)^th\) worker joined. The work was completed in mx days after the \(m^th\) worker joined. The \(1^st\) worker received a share of $5500 out of the total $38500 paid to the group for completing the work. Find m.

a. 9
b. 10
c. 11
d. 22
e. 23

At first, we calculate the CP of mixture. CP = [SP/(100+% profit)]*100 = 15.60*100/120 = 13/-.

Now, look at the cost prices of 3 varieties of rices. These CPs are 10, 12, and 17. The mixture CP=13 is closest to II variety of rice (12). [Concept of weighted average]
We can infer that among all 3 varieties, II variety ratio would be highest. Clearly, options A, B, & C are eliminated, because in all 3 options III variety ratio is highest. So the answer would be either D or E. Let's try with option D.

As per option D. CP of mixture would be.. =(2*10+6*12*3*17)/(2+6+3) = 13. It means option D is the correct answer.

hey hw many questions do we actually have here?

Posted from my mobile device

What about the lines which have no arrows? Are both directions permissible there?

As you have mentioned, this question is CAT relevant. The study material of CAT and that of GMAT are quite different. Although basic concepts are the same, it is not advisable to use CAT material for GMAT because it complicates things for no reason. There are a ton of things you need to 'know' for CAT which you don't need for GMAT. Your starting point in a CAT question is much ahead of your starting point in a GMAT question. Hence, this question isn't very relevant as far as GMAT is concerned.

Nevertheless, if you do get something like this, remember that you can solve by making the diagram according to your needs in PS questions.
Make the two circles equal so that you can easily see the required angle. Mind you, GMAT doesn't have 'cannot be determined' as an option.


You can see that it is an isosceles triangle with the ratio of the sides as \(\sqrt{2}R:\sqrt{2}R:2R i.e. 1:1:\sqrt{2}\). Hence it must be a right triangle and the required angle must be 90 degrees.

If the required angle is 90 in this case, it will be 90 no matter how you draw the diagram.

Just make a tree quickly.
From A you can take 2 different paths - B or D.
From B you can take 4 different paths - C, F, E, D.
From D you can either go to C or E and so on.
Continue till you reach F in every arm.


Each F at the end will be reached through a different route.
Count the Fs at the end. You get 10 different routes.

A father starts from home at 3:00p.m. to pick his son from school at 4:00p.m. One day the school got over early, at 3:00p.m. The son started walking towards home. He met his father on the way and both returned home 15 minutes earlier than the usual time. If the speed of the father is 35 km per hour, find the speed of the son (in km/hr).

Dear Karishma,
I do agree with you on the above fact and I would be very thankful to you if you could give a comparision between the Verbal section of GMAT & CAT as well as the IR section of GMAT with DI section of CAT. I am particularly tensned about the IR section. Since I have given CAT once, I know its reasoning section is highly tricky and tough. So do I need to put in the same level of effort for IR section??
Thanks in advance...

The two tests are not very comparable but I can give you my thoughts.

Verbal Comparison -
RC is similar in both the tests though I feel GMAT RCs are easier on average.
GMAT has CR which is not there in CAT. It's very logical and easy to get through using reasoning skills.
The SC section is tougher in GMAT than any section that tests grammar in CAT.

The IR section of GMAT is very new and hence untested. The questions will not be very tough. Once you get the hang of what to do in them, they should be fairly easy - certainly much easier than some DI questions that CAT can throw at you. Try some IR sample questions here: https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/integra ... questions/

The point is, GMAT needs logic and reasoning. If your concepts are clear, there is no reason you wouldn't be able to figure the questions. CAT is a much harder test since you need to 'know' a lot of things.

Thanks a ton!! really helpful.......
