- coprime nos to 6 in 1200 => 6=2*3.... so 1200(1-1/2)(1-.... 1s.

I learnt it somewhere , wanted to share it :
example 1 => trick for a<= b<= c<= d<= ....<=n
number of ways in which 5 numbers or n numbers can be selected from 1 to 9 , such that a<= b <= c <= d <= e
is 13C5
solution :
a will always be less than b+1
b will always be less than C+1
c < d...

I learnt it somewhere , wanted to share it :

example 1 => trick for a<= b<= c<= d<= ....<=n

number of ways in which 5 numbers or n numbers can be selected from 1 to 9 , such that a<= b <= c <= d <= e

is 13C5

solution :

a will always be less than b+1

b will always be less than C+1

c < d+1 and so on

in short ,

a < b+1 < c+2

as max value is 9 , so , e+4 can be 9+4 = 13 maximum

in short , select any 5 numbers from 1 to 13 viz 13C5

I need help!!!! I am appearing for CAT for the first time and I am not really hoping for IIM-A,B,C. My aim is new IIMs maybe MDI being realistic this way. Well my minimum benchmark is IMT.

Hey guys with the recent change in online mocks of CL according to the new pattern of CAT-2014 the previous ones have been removed,so can anyone provide me with those previous mocks (*proctored* or *unproctored*) for download as I had not given many of those unproctored.

There are three liquids X,Y and Z. Cost price of 100ml of liquid X and selling price of 100ml of liquid Y are the same, which is Rs 500.

There are three liquids X,Y and Z. Cost price of 100ml of liquid X and selling price of 100ml of liquid Y are the same, which is Rs 500. Liquid X, when sold yields a loss of 10% and Liquid Y, when sold, yields a profit of 10%. Z's cost price and selling price are the same, which is Rs 500 for 100ml.Three types of products(P1,P2,P3) are prepared in following manner-

1. P1 contains X and Y in the ratio 3:2 by volume.

2.P2 contains X and Y in the ratio 2:3 by volume.

3. P3 contains only Z

The selling price of each of the products is the aggregate sum of the selling price of the individual components.

Q1- A new mixture is formed by mixing 100ml of each of three products P1, P2 and P3. What will be the profit/loss, if this new mixture is sold?

-Loss Rs4.54

-Profit Rs 4.86

-Profit Rs 3.53

-Loss Rs 3.53

Q2- If 341ml of P1 was sold, then profit/loss would be

-1%loss

-2.5%loss

-1%profit

-2.5%profit

@MJ477 , all bank exams have the same interface , TCS only conducts them , so they are predicting it to be the same , btw they just missed this very imp factor that , bank exams hardly charge , 500/- and CAT 1600/- , so kuch toh change hoga apart from the austere invigilation.

24Comments15 and 6 both ke coprime nikalna h esliye 2 se multiply kiya h.

http://totalgadha.com/mod/forum/discuss.php?d=1483 @NinjaTurtle SIR es link pe jaeye .......yahi question diya h............i hope it helps u.

coprime nos to 6 in 1200 =>

6=2*3.... so 1200(1-1/2)(1-1/3) = 400------1

coprime nos to 15 in 1200 => 1200*(1-1/3)(1-1/5) = 640-----------2

Now in 1and 2 both coprime to 6 and 15 are counted which are,

1200(1-1/2)(1-1/3)(1-1/5) = 320--3

320 is counted in both 400 and 640 so

400-320 + 640 - 320 = 400new comments
