bhai what do you mean>>>?? bhai what do you mean>>>??@viewpt said:Q?
Aman, Baman and Chaman can finish a job working alone in 15, 20 and 25 days respectively.However, while working with somebody the efficiency of Aman, Baman and Chaman reduces by30%, 20% and 50% respectively. If none of them is allowed to work for three consecutive days, thenwhat is the maximum possible fraction of the job that they can complete in four days?a)21/50 b) 17/50 c) 8/25 d)1/3
@Dexian said:ok can u share the approach.........
the sequence will be........(a+b+c)->day 1 =32 units
a ->day 2 =20 units
b+c ->day 3 =18 units
a+b+c ->day 3 =32 units
a and b are natural numbers such that a > b > 1. If 8! is divisible by a2 — b2, then how many such
sets (a, b) are possible?
(a) 5 (b) 6 (c) 7 (d) 8
sets (a, b) are possible?
(a) 5 (b) 6 (c) 7 (d) 8

total work=300
Aman does=20
Baman=15 Chaman=12
after reduction no. of days taken=aman=14 Baman=12 chaman=6
1stcombination Aman Baman Chaman
2nd= aman Baman
3rd Chaman
4th= Aman Baman Chaman
for above 4 days =102
so, 102/300=17/50
Aman does=20
Baman=15 Chaman=12

sir jee this is wat i asked......... in that earlier post..
the sequence.....
ABC
AB

the sequence.....
ABC

I realise people are knee deep into solving stuff here, but please help me out!! I am working and have a stressful job. I am bad at quants and DI, and pretty decent in VA and LR. so,
1. How do I start, how much should i aim to put in a week?? (will need buiding up concentration)
2. Is there any text or ebook I can use for basics coz i am shot
3. I have joined classes at C, but not attending them since the past month almost coz of crazy work, but I plan to resume...yet, is self studies good enough to crack cat??
Thank you!!

bhai is approach se bhi 17/50 hi aayega...
a + b + c = 14 + 12 + 6 = 32
a + b = 14 + 12 = 26
c = 12 (doing alone with 100% eff.)
a + b + c = 14 + 12 + 6 = 32
total unit = 32 + 32 + 26 + 12 = 102
fraction of job completed = 102/300 = 17/50
@viewpt said:14+12+6)+ 14+12)+12)+14+12+6=106
ha mene wrkng alone ki efficiency bhi kam le li thi..
