@YouMadFellow Bhai I have another 15 days for CAT. Should I solve past years questions or last years mocks? I have last years aimcats, haven't taken them yet.

30*2/3*3/4*4/5*5/6*6/7*7/8*8/9*9/10
all ther terms get canceled except for 2/10 so 30*2/10 = 6
all ther terms get canceled except for 2/10 so 30*2/10 = 6
@ad18 Bhai.. I have no idea.. Even I am here at 4:18 am.. thinking should I watch the "gangnam style" video or Study "venn diagrams" ! ..

Previous year Aimcats have some good ques but no need to do all those papers. You can have a quick look provided your basics are tight by now. If not, then finish the syllabus first. I think revising this year mocks which uve given is better as you will not repeat those mistakes. Previous cat papers are also worth looking at I believe.

See, initially we have 30L
after every turn we are adding +10 quantity (-10+20= 10)
Forget abt water, we just need wine.
when u take out 10L , u have 20L remaining so the quantity of wine left will be 30L * 20/30
Similarly in the second iteration, you are taking out 10L from 40L so you are left with 30L so quantity of wine remaining will be 30*20/30 * 30/40 ..and so on..it forms a series.
Hope it's clear now :)
