IMO B

the total money at start=the total money at end=x
at start
7:6:5
1st per have=7x/18

2nd=x/3
3rd=5x/18

at end
1st=6x/15
2nd=5x/15=x/3
3rd=4x/15

diff of
1st=x/90
2nd=0
3rd=-ve
hence only the 1st one wins
hence
x/90=12--->x=1080---->1st one has 420

Let me call them A B C they had x money in total
A had (7/18)x; B had (1/3)x and C had (5/18)x at the start
in the end
A has (6/15)x B has (1/3)x and C has (4/15)x at the start

A gained (6/15)x -(7/18)x
= x (1/90)
x/90 =12
x = 12*90
he started with (7/18)*(12*90)

60*7 = 420
IMO, B

Always borrow money from a pessimist, he doesn't expect to be paid back.

I think it was option - B

I wondered if anyone could recommend a casino hire company, we want a blackjack and roulette table at our wedding for after the meal and before the band start so that there is something to fill in the time in between as I know quite often there is a bit of lull after the wedding breakfast? I've got some quotes already but obviously a recommendation from someone would be much better!!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
