Practice Questions for CAT with Solutions

1. CAT - Distribution Set

Sahil wanted to purchase a bike and went to take test drive of Pulsar, KTM, Ninja, Bullet and Apache, he took 5 parameters to test the bike, namely, pick-up, engine power, ABS, turbo and torque. He ranked the models on five parameters pick-up, Engine power, ABS, Turbo and Torque. In each parameter, he ranked the five models from 1 to 5 such that a better model was given a numerically lower rank as compared to a worse model. No two models received the same rank in any parameter.

The following information is known about the ranks of each model in each parameter:

  1. Each model was ranked third in at least one parameter and exactly two models were not ranked first in any parameter.

3. CAT - Currency Exchange Rates

The base exchange rate of a currency X with respect to a currency Y is the number of  units of currency Y which is equivalent in value to one unit of currency X. Currency exchange outlets buy currency at buying exchange rates that are lower than base exchange rates, and sell currency at selling exchange rates that are higher than base exchange rates.

A currency exchange outlet uses the local currency L to buy and sell three international currencies A, B, and C, but does not exchange one international currency directly with another. The base exchange rates of A, B and C with respect to L are in the ratio 100:120:1. The buying exchange rates of each of A, B, and C with respect to L are 5% below the corresponding base exchange rates, and their selling exchange rates are 10% above their corresponding base exchange rates.

The following facts are known about the outlet on a particular day:
1. The amount of L used by the outlet to buy C equals the amount of L it received by selling C.
2. The amounts of L used by the outlet to buy A and B are in the ratio 5:3.
3. The amounts of L the outlet received from the sales of A and B are in the ratio 5:9.
4. The outlet received 88000 units of L by selling A during the day.
5. The outlet started the day with some amount of L, 2500 units of A, 4800 units of B, and 48000 units of C.
6. The outlet ended the day with some amount of L, 3300 units of A, 4800 units of B,and 51000 units of C.

Q1. How many units of currency A did the outlet buy on that day? [TITA]

Q2. How many units of currency C did the outlet sell on that day?

4. CAT - Sitting Arrangement

In a competition, six pairs of chairs were arranged in such a way that one chair in each pair faces south and the other faces north, with the backs of every pair of chairs tied together. Thus any person sitting in a north facing chair cannot see any of the persons sitting in the south facing chairs and vice versa. The pairs of chairs were numbered from 1 to 6, from west to east, such that, both the chairs (i.e., the north facing chair and the south facing chairs) at the west end are numbered 1 and so on, till both the chairs at the east end are numbered 6.Six men – A through F – along with their wives – P through U – not necessarily in the same order, participated in the competition. All the men sat in the chairs that were facing north and all the women sat in the chairs facing south. Each of the men was provided with a paper on which he was asked to write the number of the chair on which his spouse was sitting. The following are the replies by each of them: A – 4, B – 4, C – 5, D – 6, E – 1 and F –3.

Further, it is known that

6. CAT - Investment Families Set

The investment portfolios of certain business families included mutual funds of two categories: Equity and Debt. To take care of the flip side of the market, these business families had come out with a proposal to create a contingency fund, the funding of which would be done by each business family on a monthly basis through withdrawals from the mutual funds that these families had. It was decided that the withdrawal from each Equity fund would be either Rs. 1,000 or Rs. 2,000 every month, the amount remaining the same for every Equity fund for that month; and that from each Debt fund would be Rs. 2,000 or Rs. 3,000 every month, the amount remaining the same for every Debt fund for that month. This would hold good for all the business families. The collection details of various business families are as shown in the table :

Further details on collection as observed for first five months were as given below:
Rs. 2,000 was withdrawn from every fund of every Business family for exactly two months, which were necessarily different for each family. For each of the remaining three months, within any business family, the amount withdrawn from one Debt fund did not equal the amount withdrawn from one Equity fund. Moreover, the combination of amounts withdrawn was not repeated; i.e. if B1 had withdrawn Rs. 2,000 from Equity Funds and Rs. 3,000 from Debt Funds in the month of January, then B1 cannot withdraw the same combination of Rs. 2,000 from Equity and Rs. 3,000 from Debt in any other month.
B1 withdrew Rs. 2,000 from every fund in the 1st and 2nd month.
B2 withdrew Rs. 2,000 from every fund in the 2nd and 3rd month.
B6 withdrew Rs. 2,000 from every fund in the 2nd and 4th month.

The diagram shows the racetrack for a certain motor race. There are 8 nodes in the circuit. Each node is identified by a number. There are also roads connecting the various nodes. Each road is identified by a letter. Each road also has an associated time of travel (in minutes) that is a positive integer. This time of travel is the same for a road every time it is traversed. Only one road has a time of travel that is less than 3 minutes.

A race is defined as a journey that starts from node 1 or 2 and ends at node 8 by traversing only the roads shown on the diagram.

The test driver for a particular car company does 5 test races, all of which have different routes. The information collected by him from the five races is summarized in table 1.

Further, it is known that there is an oil spillage at two of the nodes. It is not known which these two nodes are. It is known, however, that there is no oil spillage at nodes 2 and 8. An oil spillage at a node means that a car passing through that node will suffer a 2 minute increase in its total race time
