CAT 2004 Question Paper

Since  X axis gives expenditure we have to see if average is as right as possible. Average expenditure of dubey family is rightmost. Hence, option D. 

From the graph we can clearly make out that for dubey family in both the months income is nearly equal to expenditure, thus hey have lowest savings. 

To have highest amount of savings, income should be high and expenditure should be low. For ahuja family the gap is highest . Hence they have highest amount of savings

On day 3,

2 people were from university 4 and 1 person was from university 6.

2 people were from Uk and 1 person was from USA.

Hence University 4 = UK

and University 6 = USA

On day 2,

1 person was from university 3 and 2 people were from university 8.

1 person was from the Netherlands and 2 people were from India.

Hence, Univerisity 3 = Netherlands

University 8 = India

On day 1,

1 person was from University 1

1 person was from University 5

2 persons were from university 2

2 people were from university 7.

1 person was from India

1 person was from the Netherlands

2 persons were from Canada

2 persons were from the UK.

Hence University 1 can be from India/ Netherlands

University 5 can be from Netherlands/ India

University 2 can be from UK/ Canada

University 7 can be from Canada/ UK.

According to given conditions there are following possibilities of university belonging from specific country .

We can clearly make out that University 5 belongs to India or Netherlands but not USA. Hence option A.

According to given conditions there are following possibilities of university belonging from specific country .

We can see that University 1 can belong to Netherlands out of the given options.

According to given conditions there are following possibilities of university belonging from specific country .

Thus we can see that no country can can possibly host three of the eight listed universities.

On day 3, there were 2 visitors from UK and 1 from USA. On the same day, the site was visited by 2 persons from University 4 and 1 from University 6. So University 4 is located in UK and University 6 is in USA. Similar reasoning for day 2 gives us the conclusion that University 3 is located in Netherlands and University 8 is in India. On day 1, the number of visitors from USA is 1 and that from University 6 is 1. University 6 is in USA (derived above), which implies no other university is in USA. The number of visitors from India on day 1 is 1. Also, no visitor from University 8, which is in India has visited the site on day 1. This implies that one of University 1 and University 5 is in India and the other in Netherlands. A similar logic gives us that one of University 2 and University 6 is in UK and the other in Canada.

We can see that university 4 and university 7 from UK visited prof. Singh's homepage in the three days.

There were 30 naya mixture in 97' which will also work in 98' ,thus we have 50 new mixtures in 98' . Now in 99' 20% of 30 i.e. 6 are thrown in junk . So in 99' we have 24 + 50 = 74 naya mixtures of previous years. So naya mixture grinder purchased in 99' is 124-74 = 50. Hence option b. 

Number of Naya mixer-grinders were disposed off by the end of 1999 are 6 and at the end of 2000 are 10. So in total 16 naya mixer disposed off. 

Since 10 purana were disposed off in 1997, it means 50 new have been bought in 1995, which implies that 70 were already in use. The breakup of 70 purana cannot be determined. So the number of purana disposed in 2000 cannot be calculated.
