hi there....i don't know in which forum to post this but could anyone give the answer and explanation to the following question :


All good atheletes who want to win are disciplined and have a well balanced diet. Therefore, atheletes who do not have well balanced diets are bad atheletes.

Based on the sentence above which of the following strongly supports the view:

a) no bad athelete wants to win

b) no athelete who does not eat a well balanced diet is good athelete

c) every athelete who eats a well balanced diet is good athelete

d) all athelete who want to win are good atheletes


from where u got this q???

i will go with C
A is not correct- in statement its given that "atheletes who do not have well balanced diets are bad atheletes"..but its not mentioned that they dont want to win
B-
D- repeated sentence
----
whats the answer???
"Impossible", "give up" are not in my dictionary --------

Alok and Bhanu play the following min-max game. Given the expression
N = X Y Z

Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of his choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?


with answer please tell your solving approach as well.

It took me some time to understand what question really meant

Ok since Alok it trying to maximize lets assume Alok chooses a value of 9. For this Bhanu who is trying to minimize will choose this as z. So whatever value Alok chooses it would not result in highest.

If Alok chooses 0, then bhanu will substitute to x, so from here on whatever value Alok chooses it would end in negative. Same applies for 1.

Now think, if Alok go for 5 Bhanu would substitute it to either yorz bcoz if he chooses x then alok will go for 0 and 1. Which would result in value of 4.. Bhanu will not make that blunder. Now Alok cant choose any value less 5 because bhanu would substitute that value to x(negative answer). Which would mean whatever u select later in range of 6-9 will result in negative value. This holds true for 6,7,8,9..

So values left are 2,3, and 4.
If alok chooses 2, bhanu will substitute this to z(think urself why not for x?). From here Alok can choose 4(think why not 3?) for which bhanu will subtitute in either x or y(doesnt matter, I will go for x). For third value alok will go for 0 (in case of x that is)which automatically substitutes itself to y, resulting in max vaue of 2.

If alok chooses 3, bhanu will substitute this to z, From Alok can only go for a value of 4 or 5 for which bhanu should substitute in x in case of 4 . For third value alok will go for 0 in case of 4 which automatically substitutes itself to y, resulting in max vaue of 1.

For 4 u can get max value of 0..

Hence optimum value could be 2...

Now whats the OA?

Something seems to be wrong in this question...`

J=10
U=21
D=4
G=7
E=5

We need the product to be 10*21*4*7*5

and we cant re use J,U,D,G,E...

We need two 7's for products to match.. but we only got one 7 (N=14)....


its FANNY..
From 1, the name of his wife had a product of 10*21*4*7*5.

From 2, her name does not contain G(7) or U(21). So it has to contain N(14) twice. Dividing the product by 14 twice, leaves 10*3*5 as the remainder.

From 2, her name doesn't have E(5) or J(10). It cannot have a T(20). Also, it cannot have I(15).

So, it can have Y(25). On dividing y 25, we get 2*3.

From 3, her name cannot have C(3). Hence, her name has an F(6).

In the alphabetical order, the letters spelled FNNY. The only other letter that the name can contain is A(1). This also leaves the product unaltered.

So, from 4, his wife's name is Fanny...

NEXT KOSHEN:
Denise needed a date for her prom. However, she has only one criterion for a date - "He should be tall, dark and handsome."

She considered Angad, Bobby, Chirag and Devesh as prospective candidates.


1. Of the specified traits viz, tall, dark and handsome, no two of the four guys possess the same number of traits.

2. Only Angad or Devesh is fair and also tall.
3. Only Bobby or Chirag is vertically challenged yet handsome.
4. Angad and Chirag are either both short or both tall.
5. Bobby and Devesh are either both fair or both dark.

Among the boys, who do you think is eligible to be chosen as her date?


yaar simple language main try karta hun samjhane ki

sabse pehle condition 2 main suppose kiya
angad-fair n tall hai...ok
ab condition 4 dekho kya keh raha hai
dat means chirag bhi tall hoga....k
now check 3rd one either bobby or chirag is vertically challenged yet handsome....ab chirag ye nahi ho sakta bcoz ye pehle hi conclude ho chuka hai ki wo tall hai.....
ab humare paas three conclusions aa gaye
1.Angad-fair,tall
2.Chirag-tall
3.Bobby-short(vertically chlg),handsome
isse ye clear ho gaya ki angad aur bobby nahi ho skte
reh gaye chirag aur devesh...

ab humko 1 condition use karni hai jiska imp role hai..
case 2 hai devesh ya to fair or dark agar devesh dark hai to contradict hota hai....ab itna main samajha nahi skta kaise.....hahaha.....chal ab suppose karo ki devesh is fair...agar devesh fair hai to bobby bhi fair hoga acc to cond 5
haan to ab conclude hua..
angad-fair ,tall
chirag-tall
bobby-short.handsome,fair
devesh-fair
ab clear hota hai ki chirag dark hai...aur contradict bhi nahi ho raha

Here comes final ans
angad-fair,tall,handsome
chirag-tall,dark,handsome
angad-short,handsome,fair
bobby-fair,not handsome,not tall
ye saare ans 1st condition ko support karte hai means out of 3 specified traits-dark,handsome an tall koi bhi 2 boys same no. of traits possess nahi karte
angad-tall n handsome(2 trait)
chirag-all three(3 traits)
angad-handsome hai(1 trait)
bobby-koi bhi trait nahi hai(0 traits).....

hehehehehe......

options a and d are totally out no match i.e dont support d statement so options left are b or c
Correct ans is Option B whynot C bcoz its not alwayz true dat if an athlete takes well balanced diet he is also a good athlete but good diet is must for athlete to be good

I hope its clear

Bhai kaisi complicated ladki hai :biggrin: Yeh koshan solve karne se accha, date pe hi mat jaao :grin:. Ok on a serious note. I guess that lucky boy would be Chirag. 1st and 3rd condition are the important one. Here is the matrix.
Columns represent names A=Angad,B= Bobby, C= Chirag and D= Devesh. Rows represent D= Dark, T=Tall, H= handsome. The matrix entry represent Y=Yes, N=No.

* :: D----T----H
---------------------
A :: N----Y----Y

B :: N----N----Y
|
C :: Y----Y----Y

D :: N----N----N

Koi condition fail to nahi ho rahi naa:lookround::lookround:

J * U * D * G * E = 10 * 21 * 4 * 7 * 5 = 5^2 * 2^3 * 7^2 * 3
Now 7 cant go with 5 and 3. Hence the only option is 7*2 =14. Since there are two factors of 7 there will be two 14's. After getting these two letters we are left with 5^2 * 2 * 3. 5 can't go with 2 or 3. Hence only option is 5^2 = 25. Now we are left with 2*3. They both can't be taken individual as 3 is unlucky for the judge. Hence the only option left is 2*3 = 6. So final values are ( 14 , 6 , 14 and 25 ). The name is NFNY. (Aise naam ko pronounce kaise karenge ?? ) What is the OA??

Next koschen:

Edwin retired last week from the post of a judge in the Supreme Court. He believed completely in numerology and, hence, his wife's name also fulfilled certain conditions in numerology.
1. Her name has a product that is the same as the product for "Judge". (The product for judge is J*U*D*G*E)
2. Her name does not have a single letter of the alphabet common with the word "Judge".
3. Her name did not contain the third letter of the English alphabet as he considered 3 to be an unlucky number for him.
4. If the first and second letters in her name were interchanged, the letters in her name would be arranged in the alphabetical order.

Use A = 1, B = 2 and so on.

What was his wife's name?


Something seems to be wrong in this question...`

J=10
U=21
D=4
G=7
E=5

We need the product to be 10*21*4*7*5

and we cant re use J,U,D,G,E...

We need two 7's for products to match.. but we only got one 7 (N=14)....


its FANNY..
From 1, the name of his wife had a product of 10*21*4*7*5.

From 2, her name does not contain G(7) or U(21). So it has to contain N(14) twice. Dividing the product by 14 twice, leaves 10*3*5 as the remainder.

From 2, her name doesn't have E(5) or J(10). It cannot have a T(20). Also, it cannot have I(15).

So, it can have Y(25). On dividing y 25, we get 2*3.

From 3, her name cannot have C(3). Hence, her name has an F(6).

In the alphabetical order, the letters spelled FNNY. The only other letter that the name can contain is A(1). This also leaves the product unaltered.

So, from 4, his wife's name is Fanny...

Even i'm getting NFNY
@praks1529- Just made up a rather funny expansion for NFNY-"Neighbours' Forever Never Yours!!"

The trouble with being in the rat race is that even if you win, you're still a rat
