@bodhi_vriksha said:One more:4 couples of husband-wife go to a dance party where they are supposed to dance in pairs. They decide that no one will dance with his/her partner. In how many ways all of they can be paired?Remember that it is 21st century and a man can be paired with man and similarly a woman can also be paired with woman.
Dearrangements
4! ( 1- 1/1! + 1/2! -1/3! + 1/4! ) = 9 ?
Is the answer = 9 + 12 = 21 ?? .. @bodhi_vriksha
P.S. : Sorry Did not see that man-man and woman-woman is possible

sp = y
cp = x
y - x/x = 10/100
(y - 132) - .9x/.9x = 10/100
y - x/x = (y - 132) - .9x/.9x
y = 1320
1320 - x/x = 10/100
x = 1200 ?

ye lo approach @mailtoankit bhai ne post kar di
@vbhvgupta said:@DeAdLy are bhai approach bhi post kar dia karo
jugaadi approach hai....
100 rs agar price hai, to 110 pe bikta hai.
agar 90 pe liya hota aur 99 pe becha hota to bhi 10% munafa hota aur CP mein 11 rs ka difference hai. problem mein 132 ka difference hai i.e.12 times 11. so sab 12 times hoga. so 100*12=1200
@sa1m007 said:Please anyone solve this !!
whats the OA for the first one...
here is the approach , if the OA is correct you can try all the others similarly..they are on similar lines with slight deviations ...
Approach :
salary = add up all the components * 12 = 733200
HRA component ;
you have to choose the least of
.4*40,000 , actual HRA, rent paid..
the least comes out to be rent paid = 12,200
so for 1 yr 12,200*12= 156240
Medical exempt = 0
conveyance exempt = 800*12 = 9600
total exempt = 733200 - (12200+9600)
576960
now
0 to 1.5 lac tax = 0
1.5 to 3l = 1.5l *10% = 10k
3l to 5l = 2l*20% = 40k
5l onwards = .76960l *30 % = some value
on adding approximately around 78,088
There are some clculations error...but the basic funda of tax calculation is this...
if the answer is near about to the OA...you can try out the rest..
else lemme know..will check again...
P.S. : questions like this will not come in CAT(highly unlikely) ..you can expect them in XAT though, If I am not wrong XAT 2011 had a similar question...

Q: A manufacturer claims that only 2 % items are defective in a shipment of 200. A random sample of 2 items is drawn from shipment of 200 items. What is the probability that both items drawn are defective?
a: 3/19900
b: 6/19900
c: 9/19900
d: 8/19900
@saurav205 Thank u for ur reply ......... and that is not OA .......... it is DA ........ Dearness Allowance

OA is DA??
That was not even in the options man...:)

aesa kuch options main nai diya na lekin... I am also getting the same .
@viewpt said:40C2/ 200C2 ??
arey i wrote 20 instead of 2%
. ur approach is correct as well as answer according to 20%.
