Quantitative questions a day 51 to 100 - The discussions

[catter2006]

c + m + b = 42
c + 3/4 * 1/2 * c + 1/2 * c > 42
c > 22.4 => c >=23
m>=8
b >=5

c + m + b = 42
2b + 2/3 * b + b < 42
b < 11.4 => b <= 11
m<=8
c<=23

m=8, c= 23, b=11

Ans = (a) - 3 more banana's.

i need to do this faster how ???

m=3b/4-x=3c/8-3k/4-x
Now c , m and b have to be integer. c must be of the form 24n.So c must be=24
Now m+b=18 becoz c+m+b=42
Now b must be 4,8,12,or 16.But as b is less than half of c it has to be less than 12 ie b=4 resulting into m=14 which is not possible becoz as indicated from third eqauation m<b

So the given scenario is not possible
hope i make some sense..

amar bhai i couldn't understand y u r takin c to be of the form 24 n
put c=23,b=11,m=8 thn also ur eqns are satisfied only i think the k,p,x vals will be decimals,not pure integers.....
if we take 2b=c-k then k has to be an int,
thatz what i think,may b i m incorrect...

All is well till the assumption in RED.. remember x and kneednt have to be integers

My soln

take chikkoo number as K
K + ( 1/3K + 1) + [4/3 (1/3 K +1) +1] = 42

16/9 k + 10/3 ~ 42
k~ 38 *9 /16
k ~ 2.4 *9
k~22.mm
trial and error around 22
chik ban man
23 11 8

Ans a)3

Tht's what i am doubting. See when we say bananas are less than half of chikoos, it has to be less by integer no only naa.It can be 1or 2 or3 or4 ...less the half of chikoos. Being less than half of chikoos by a fraction quantity doesn't make sense practically, though in equation form it looks okay becoz here we are dealing with numbers of chikoos, banananas and mangoes and they always come in integer values.

This can a result of my skewed thinking...

haan ,i think practically it has 2 b int ,actually first i had strtd workin the way u hav done,then i thaught if we adhere 2 pure mathmtcl way thy can b both frctn n int...
Letz c wht aarav n othr junta say...
BTW i hav ths doc of urz havin 100 odd qs,r u discussin the same in da mindblowin...second season thrd????

Not necessarily. But i am trying to pick up those questions of previous MB thread which were not solved, and some new problems from other sources too...

Hoping for your active participation out there..

My advice here would be that you guys go thru each and every problem discussed in the mind-blowing section. It helped us a lot in CAT 2005. Almost 10 mark questions were from the very questions we discussed there. There are I guess 200 problems there, pick them up in order and start discussing. You can always look back at the solutions in the original thread

Thik hai fir..ulti ginti se suru karte hai. I think it will be okay if we move backwards from the 5oth page to first one of previous MB thread. ..Hope tht will be okay...

Aap logon ka answer theek hai, this was a problem where some hit and trial is required.

As you wish But make sure you discuss most of the problems out there.
