TITA Based Questions: Grouping and Selections
As TITA (Type In The Answer) based questions are gaining prominence in the CAT exam, it's important to build accuracy without relying on options. The following are carefully curated TITA-based questions on the topic Grouping and Selections to help you practice exact value-based problem solving.
Que 1: Instructions for Set 1
Three reviewers Amal, Bimal, and Komal are tasked with selecting questions from a pool of 13 questions (Q01 to Q13). Questions can be created by external "subject matter experts" (SMEs) or by one of the three reviewers. Each of the reviewers either approves or disapproves a question that is shown to them. Their decisions lead to eventual acceptance or rejection of the question in the manner described below.
If a question is created by an SME, it is reviewed first by Amal, and then by Bimal. If both of them approve the question, then the question is accepted and is not reviewed by Komal. If both disapprove the question, it is rejected and is not reviewed by Komal. If one of them approves the question and the other disapproves it, then the question is reviewed by Komal. Then the question is accepted only if she approves it.
A question created by one of the reviewers is decided upon by the other two. If a question is created by Amal, then it is first reviewed by Bimal. If Bimal approves the question, then it is accepted. Otherwise, it is reviewed by Komal. The question is then accepted only if Komal approves it. A similar process is followed for questions created by Bimal, whose questions are first reviewed by Komal, and then by Amal only if Komal disapproves it. Questions created by Komal are first reviewed by Amal, and then, if required, by Bimal.
The following facts are known about the review process after its completion.
1. Q02, Q06, Q09, Q11, and Q12 were rejected and the other questions were accepted.
2. Amal reviewed only Q02, Q03, Q04, Q06, Q08, Q10, Q11, and Q13.
3. Bimal reviewed only Q02, Q04, Q06 through Q09, Q12, and Q13.
4. Komal reviewed only Q01 through Q05, Q07, Q08, Q09, Q11, and Q12.
Q1: How many questions were DEFINITELY created by Amal?
Q2: How many questions were DEFINITELY created by Komal?
Q3: How many questions were DEFINITELY created by the SMEs?
Q4: How many questions were DEFINITELY disapproved by Bimal?
Que 2: Instruction for Set 2
K, L, M, N, P, Q, R, S, U and W are the only ten members in a department. There is a proposal to form a team from within the members of the department, subject to the following conditions:
- A team must include exactly one among P,R and S.
- A team must include either M or Q, but not both.
- If a team includes K, then it must also include L, and vice versa.
- If a team includes one among S, U and W, then it should also include the other two.
- L and N cannot be members of the same team.
- L and U cannot be members of the same team.
The size of a team is defined as the number of members in the team.

Que 3 : Instructions for Set 3
Two traders, Chetan and Michael, were involved in the buying and selling Of MCS shares over five trading days. At the beginning of the first day, the MCS share was priced at Rs 100, while at the end of the fifth day it was priced at Rs 110. At the end of each day, the MCS share price either went up by Rs 10, or else, it came down by Rs 10. Both Chetan and Michael took buying and selling decisions at the end of each trading day. The beginning price of MCS share on a given day was the same as the ending price of the previous day. Chetan and Michael started with the same number of shares and amount of cash, and had enough of both. Below are some additional facts about how Chetan and Michael traded over the five trading days.
- Each day if the price went up, Chetan sold 10 shares of MCS at the closing price. On the other hand, each day if the price went down, he bought 10 shares at the closing price.
- If on any day, the closing price was above Rs 110, then Michael sold 10 shares of MCS, while if it was below Rs 90, he bought 10 shares, all at the closing price.
Q1: If Chetan sold 10 shares of MCS on three consecutive days, while Michael sold 10 shares only once during the five days, what was the price of MCS at the end of day 3?
Ans: Rs 110
The above table includes the values of the share price at the end of each day. Chetan and Michael column shows the number of shares at the end of 5th day with Chetan and Michael respectively. (-10 means he has sold 10 shares, +10 means he has bought 10 shares) there are 10 different possible cases according to the initial and final share price.
The question asks about the case where Chetan has sold 3 times and Michael sells only once.
Starting with Michael, for exactly one sell, the price should touch 120 only once as Michael sells the share only at price greater than 110.
if the price touches 120 twice or more, Michael will sell the share more than once which is not a desirable case.
Also, chetan has to sell thrice consecutively which is only possible if the share price is 90 at one instance and rises to 120 in straight 3 days.
This is only possible in case 2. Hence the price on 3rd day's end in case 2 is 110.
Q2: If Chetan ended up with Rs 1300 more cash than Michael at the end of day 5, what was the price of MCS share at the end of day 4?
Ans: Rs 100
The above table includes the values of the share price at the end of each day. Chetan and Michael column shows the number of shares at the end of 5th day with Chetan and Michael respectively. (-10 means he has sold 10 shares, +10 means he has bought 10 shares) there are 10 different possible cases according to the initial and final share price.
Please note that Chetan will always be having -10 shares(10 shares sold) and 1300 as cash.
This is because Chetan buys for every fall in price and sells for every rise in price. But the fluctuation in share price is constant as it starts from 100 and closes at 110 on day 5. So, in total Chetan will always sell 10 shares in all 5 days combined.
As Chetan has sold 10 shares, he'll get 110*10 =1100 cash because of it in every case. Also, Chetan earns Rs. 200 in every case because of buying at low and selling at high. So total cash Chetan will always have after 5 days = 1100+200 =1300.
The question asks about the case where Michael ended up with Rs 1300 cash less than Chetan.
As Chetan will have exactly 1300 cash in every case; we have to look for the cases where Michael does not make any profit and also does not have any sold shares at the end of 5 days.
This is possible in 4 cases ie. 3,4,5 and 9.
In each of these cases, the price fluctuates in the range 90-110 which does not allow Michael to buy or sell any shares.
Also, in all these cases the price of MCS is 100 at the end of day 4.
So the answer is 100.
Q3: What could have been the maximum possible increase in combined cash balance of Chetan and Michael at the end of the fifth day?
Ans: Rs 5000
The above table includes the values of the share price at the end of each day. Chetan and Michael column shows the number of shares at the end of 5th day with Chetan and Michael respectively. (-10 means he has sold 10 shares, +10 means he has bought 10 shares) there are 10 different possible cases according to the initial and final share price.
Please note that Chetan will always be having -10 shares(10 shares sold) and 1300 as cash.
This is because Chetan buys for every fall in price and sells for every rise in price. But the fluctuation in share price is constant as it starts from 100 and closes at 110 on day 5. So, in total Chetan will always sell 10 shares in all 5 days combined.
As Chetan has sold 10 shares, he'll get 110*10 =1100 cash because of it in every case. Also, Chetan earns Rs. 200 in every case because of buying at low and selling at high. So total cash Chetan will always have after 5 days = 1100+200 =1300.
The question asks about the case where there has been the maximum possible increase in the combined cash balance of Chetan and Michael at the end of the fifth day.
As we know chetan has 1300 cash in all the cases , so we have to maximize the case where Michael has the most cash.
Also, if we see clearly, the profit made by selling and buying is in hundreds while the cash received by selling the shares is much far in terms of cash.
As 10 shares sold give = 10*110 = 1100 cash. So we have to look at the case where Michael has sold most shares which is case 8.
In case 8 the price rises from 100 to 110 ->120 ->130 ->120 ->110
in this case 110(0 new shares)->120(Michael sold 10 shares)->130(Michael sold 10 shares)120(Michael sold 10 shares)->110(Michael does nothing) = 30 shares sold in total
Cash = 20 shares at 120 and 10 shares at 130 = 120*20+130*10 = 2400+1300 =3700
As Chetan has 1300 cash and Michael has 3700 cash;
total cash they have is : 3700+1300 =5000
Q4: If Michael ended up with 20 more shares than Chetan at the end of day 5, what was the price of the share at the end of day 3?
Ans: Rs 90
The above table includes the values of the share price at the end of each day. Chetan and Michael column shows the number of shares at the end of 5th day with Chetan and Michael respectively. (-10 means he has sold 10 shares, +10 means he has bought 10 shares) there are 10 different possible cases according to the initial and final share price.
Please note that Chetan will always be having -10 shares(10 shares sold) and 1300 as cash.
To have 20 more shares than Chetan, Michael has to buy 10 shares which is case 1.
In case 1, the share price at the end of day 3 is 90.
