Where in the question is it written that the split in profit will be according to the investment . I dont think GMAT will leave such an assumption open for test takers.

A. Rs. 1900
B. Rs. 2660
C. Rs. 2800
D. Rs. 2840

Total money invested by A,B,C respectively : 6500*6 ; 8400*5 ; 10000*3 = 39000 ; 42000 ; 30000. The split of the profit will done in the ratio of money invested. Thus, the ratio = 13:14:10. Also, the total profit to be split is the amount after giving 5% to A--> 7400*0.95. B's share : $$\frac{14}{37}*7400*0.95$$ = 14*0.95*200 = 2660.

B.

Is there an easy place here to round that I missed? The math on this took me forever and I don't want to be long-multiplying on the GMAT.

I got to $$\frac{42}{111} * \frac{19}{20} * 7400$$

and I got to that point after about a minute fo simplifying... blah.

You should realize that you can still factor out 3 from$$\frac{42}{111}$$, and that will give you $$\frac{14}{37}$$.Also, 37*2 = 74.So, you end up with $$14*\frac{19}{20}*200$$= 190*14 = 19*14*10. The only option with a 6 in the tens digit is B.

oh geez, good point. 3 is one of the easiest ones to spot too...

Hi Bunuel,

can you shed some light on this one ? How can we presume that profit is to be split after taking off 5% for A ? Does this type of question appear in GMAT ?

This is not a GMAT question. So, I wouldn't worry about it at all.
