A. As I gazed out at it, suddenly the indignities of the trip did not matter.

B. In the days to come, as I visited Jain temples and various other

C. But then, in the distance, like a mirage, there was Jaisalmer, its
walls and turrets golden and shimmering in the lowering sun, seeming to

D. And I was in love again with India — a love that has lasted all
these years, over repeated visits, for a country that, in its harshness
but also its magnificence, always exceeds expectations.

The paper hangs a lot. DI takes 2 minutes to load. Sometimes pages don't even load between the exam. I hope your interface is not like the actual CAT or it would be disaster for us.

@aditya0912 We hope that you did not face a similar issue while taking all the tests. If that's the case, we'll suggest that you try an alternate ISP for taking next test. Since we check all the tests while students are taking those simultaneously & we don not face any issue related to speed, we can safely say that this is not a problem that is reoccurring. Do let us know if you need any further help. & next time you face such a problem, call us immediately at 09216937105 (between 08:00 AM - 11:00 PM).

MBA Prep articlesWith about a month or so to go, the question that junta is asking at this point is not "Do I have it in me to crack C...

Problems based on grids/chessboards have been asked in the CAT and other MBA entrance exams over the years. They seem really difficult when you encounter them for the first time but once you get the hang of things they become really simple. The key lies in understanding the basic concepts involved.

The most common grid structure that we are all familiar with is the chessboard. Let us look at some of the common questions based upon grid.

**Q1. **What is the number of squares on a chessboard?

Squares of size 1x1 = 8^2 = 64

Squares of size 2x2 = 7^2 = 49

.

.

Squares of size 8x8 = 1^2 = 1

Total number of squares = **1 + 4 + 9 .. 49 + 64 = 204**

*You could have also used the formula 1^2 + 2^2 + 3^2 … n^2 = n(n+1)(2n+1)/6*

*In this case, you would have got = 8*9*17/6 = 12*17 = 204*

**Q2. **What is the total number of rectangles on a chessboard?

To form a 8 x 8 chessboard, we need 9 horizontal and 9 vertical lines.

If we select any 2 lines from the 9 horizontal lines and any 2 lines from the 9 vertical lines, we will get a rectangle

Total number of rectangles = **9C2 * 9C2 = 36*36 = 1296**

**Q3. **In how many ways can you place 2 rooks on a chessboard such that they are not in attacking positions?

The first rook can be placed in 64 ways

The second rook cannot be placed in the same row or the same column. So, it has 7 rows and 7 columns left for it. It can be placed in 49 ways.

But the order in which the rooks are placed is not important. So, it will be divided by 2!

Total ways = **64*49/2 = 1568**

**Q4. **In how many ways can you place 8 rooks on a chessboard such that they are not in attacking positions?

The first rook can be placed in 64 ways.

The second rook can be placed in 49 ways.

.

.

The eigth rook can be placed in 1 way

But the order in which the rooks are placed is not important. So, it will be divided by 8!

Total ways = **64*49*36…4*1/8! = 8! = 40320**

**Q5. **In how many ways is it possible to choose a white square and a black square on a chess board so that the squares must not lie in the same row or column? **[CAT 2002]**

The white square can be chosen in 32 ways.

If we remove the row and the column which contains the chosen white square, we will be left with 7 Rows & 7 Columns containings a total of 49 squares (24 black and 25 white). We would have removed 15 squares (7 white and 8 black)

Required ways = **32*24 = 768**

**Q6. **In how many ways can you go from A to B? (Shortest path)

To go from A to B, you need to make 4 right moves (R) and 6 up moves(U).

One of the possible paths could be RRRRUUUUUU

Any rearrangement of the above would give you a different shortest path from A to B.

RRRRUUUUUU can be rearranged in **10!/(4!6!) = 210 ways** because among the 10 entities four Rs are identical and 6 Us are identical.

Another way of solving this could be:

From the 10 moves that you have to make select the 4 moves which will be Right moves. This can be done in **10C4 = 10!/(4!6!) = 210 ways**

**Q7.** In how many ways can you go from A to B? (Shortest path)

To go from A to B, you will have to follow the path APQB

A to P can be done in 4C2 = 6 ways (Select 2 right moves from a total of 4 moves)

P to Q is only one way (The path through the red rectangle)

Q to B can be done in 3C1 = 3 ways (Select 1 right move from a total of 3 moves)

Total ways = **6 x 1 x 3 = 18 ways**

**Q8.** In how many ways can you go from A to B? (Shortest path)

Total ways (if the red rectangle was not there) = 10C4 = 210

PQ is the road which has been removed. It would make all the routes which included the road PQ as invalid.

So, all routes consisting of APQB will be invalid

A to P = 5C3 = 10

P to Q = 1

Q to B = 4C3 = 4

Invalid ways = 10 x 1 x 4 = 40

Total valid ways = **210 – 40 = 170 ways**

**[CAT 2008]** The figure below shows the plan of a town. The streets are at right angles to each other. A rectangular park (P) is situated inside the town with a diagonal road running through it. There is also a prohibited region (D) in the town.

**Q9.** Neelam rides her bicycle from her house at A to her office at B, taking the shortest path. Then the number of possible shortest paths that she can choose is

Let us call the road through park as MN.

The path Neelam will take is AMNB.

Neelam can go from A to M in 4C2 = 6 ways.

M to N in 1 way

N to B in 6C2 = 15 ways.

Number of possible shortest paths = **6*15 = 90**

**Q10**. Neelam rides her bicycle from her house at A to her club at C, via B taking the shortest path. Then the number of possible shortest paths that she can choose is

Neelam can go from A to B in 90 ways.

From B to C via N = 6 (and not via M)

From B to C via M = 7 ways

In all **90*(6+7) = 1170 ways**

I hope you enjoyed this post and if you get a grid based question in CAT, you will be able to crack it.

@2014CAT let the balls are B1 ,B2,.....B7.

Take B1 B2 B3 in one pan and B4 B5 B6 in the other.

If they weigh equal, B7 is the heavier ball. Otherwise weigh the heavier lot (let us say B1 B2 B3) were heavier. Now weigh B1 and B2. If both weigh equal then B3 is the heavier one and if they dont weigh equal, the one who weighs heavier is the heavier...!!

So answer is 2...!
