so pls note tht thr is F in the question and each alphabet represents a different digit from 1 to 9 only and thr shd b no 0

ohh thanx a lot for the clarification divya...

Plz check and confirm if the value is really Rs.3.24 as my value comes out to be in decimals and the no of handkerchiefs must be in an inetger.....

friends post the solution as soon as possible.......

thank u

can anybody plz explain to me ...under what condition a player is considered a winner....??Does a player has to have the outcome of both the coins flipped in favour of him to be declared a winner??: : :

Ans:52.5 (conversion A=(7/3)B-70)

hey divya

plz tell me how did u get this equation coz none of us got this ...thanks

some more qs
18. Four persons A, B, C and D are playing cards. Each person has one card, laid down on the table below him, which has two different colors on either side. The colors visible on the table are Red, Green, Red and Blue. They see the color on the reverse side and give the following comment.
A: Yellow or Green B: Neither Blue nor Green
C: Blue or Yellow D: Blue or Yellow
Given that out of the 4 people 2 always lie find out the colors on the cards each person.

20. Some statements are given below:

• L says all of my other four friends have money
• M says that P said that exactly one among them has money
• N says that L said that precisely two among them have money
• O says that M said that three of the others have money
• P, L and N said that they have money

All the above statement are false. Who has money & who doesn't have any money?

26. Conversation between two mathematicians:
First : I have three children. The product of their ages is 36. If you sum their ages, it is exactly same as my neighbor's door number on my left.
The second mathematician verifies the door number and says that it is not sufficient. Then the first says " Ok one more clue is that my youngest is really the youngest". Immediately the second mathematician answers. Can you answer the question asked by the first mathematician? What are the children ages?


27. 500 men are arranged in an array of 10 rows and 50 columns according to their heights. Tallest among each row of all are asked to fall out. And the shortest among them is A. Similarly after resuming that to their original positions that the shortest among each column are asked to fall out. And the tallest among them is B. Now who is taller among A and B ?

Mr Vineet.nitd, refer to your post 146. The question is clear but u are making a mistake. What is given is 14 degrees in A is 36 degres in B. and 133 degrees in A is 87 in B. If u put A as 14 in the equation what i gave, u will get B = 3*14/7 + 30 = 36 and other set also, B = 3*133/7+30 = 87 both sets are exactly amtched. Before giving any reply, please verify whether wat u are doing is right. We are doing these kind of questions for years and years and after many such posts only, we were given as Hardcore pagals. Dont make thingd as silly as this.

Sir ,
now its clear ... well, in anyways , i thought a healthy discussion wud benefit us ..i got it wrong here ..... its just out of the curosity thats wot is reflected in my post nothing else ....So , kindly excuse if it was a question to ur experience..i really dint mean so ..
nd it will be taken care of hence forth ........
thanks and regards ...

Hi Chetna,

we can express the square of length of the square surface as , L^2 =(area/6 ) [surface area of a cube is 6(L^2) ]
since one area is a and suppose if a is a multiple of 6 ..then square of the length wud have an integer value.
now since a is divisible by 6 , clearly a+5 cannot be divisible by 6 , and similarly holds for a+10.
Now in that case ..where we r sure all the length values cannot be integers , we can have many values of a which will give corresponding as many value of lengths ..
So, we cant determin a unique exact value for length ..
Hope , this is more clear from my part ..
