@simplySexy said: Two white squares and a black square has to be chosen from a chess board such that no two of them are in the same row or the column. In how many ways can the selection be made ? I have a doubt in dis ques....Should d way we select squares effect d permutation i.e. wwb or wbw.....If i select wwb den i m getting 32* 25* 18/2.(select w out of 32 w...den b out of remaining 32-7 b. ...den w from 32- 8-8+2 w....den divide by 2 as order of white squares doesnt matter)If i select wbw den i m getting 32* 24* 18/2.Oa is 32*24*18/2....Pls explain d discrepancy.
there a total of 32 black and 32 white squares. we have to find the selections of 2 whites and a black.

the first white square can be chosen in 32 ways.

the second one then will be from the 7 x 7 matrix = 25 black and 24 white =24 ways

the next black will be from the 6 x 6 matrix ( 18 white and 18 black)= 18ways

as we are talking about selections then we've to considered unordered ways so we have to divide what we get by 2.

Ans = 32*24*18/2=6912 ways

@x2maverickc said: @YouMadFellow Ans is 515

Two white squares and a black square has to be chosen from a chess board such that no two of them are in the same row or the column. In how many ways can the selection be made ?

abt CAT dates? which dates are good ? last or in between . I have given CAT last 3 times , and observed that some dates candidates do not score more.

Obviously we cannot . I just gave condition for least value of that expression when there is no constraint on x,y,z.

@[109608:shivs] I guess the answer is option 1. (6).

@shivs said: Rohan is asked to figure out the marks scored by Sunil in three different subjects with the help of certain clues. He is told that the product of the marks obtained by Sunil is 72 and the sum of the marks obtained by Sunil is equal to the Rohan ₏™s current age (in completed years). Rohan could not answer the question with this information. When he was also told that Sunil got the highest marks in Physics among the three subjects, he immediately answered the question correctly. What is the sum of the marks scored by Sunil in the two subjects other than Physics?Options : 1. 6 2.8 3.10 4. Cannot be determined

6 hona chahiye. Only one case where confusion happens sum=14

(8,3,3) and (6,6,2)

Let a be the integer such that (x + a)(x + 2012) + 1 can be factorized as a product (x + b)(x + c) where x, b, c are 足integers.

Find the sum of all possible values of a.
OPTIONS

1) 1006
2) 2012
3) 3018
4) 4024

@[574519:x2maverickc] is it 189? or is it 6327?

@[109608:shivs]
6*6*2=8*3*3=72
Also 6+6+2=8+3+3=14
Highest marks is in Phyics so it'll be equal to 8
Hence sum of rest two is
1.6

@Rage126 said: @subhakimi Can we include fractions?

What is the sum ? 10
And it is 2*5 but here we cannot find a series
But we can find a series from 4*(2.5) where 4 will represent the number of numbers in the series and 2.5 will represent the mean or average.

Are we using any fractions ? No. But we are just modifying the case 2*5 in a different case.
