Directions for Questions:
There are 21 employees working in a division, out of whom 10 are special-skilled employees (SE) and the remaining are regular skilled employees (RE). During the next five months, the division has to complete five projects every month. Out of the 25 projects, 5 projects are "challenging", while the remaining ones are "standard". Each of the challenging projects has to be completed in different months. Every month, five teams T1, T2, T3, T4 and T5, work on one project each. T1, T2, T3, T4 and T5 are allotted the challenging project in the first, second, third fourth and fifth month, respectively. The team assigned the challenging project has one more employee than the rest.
In the first month, T1 has one more SE than T2, T2 has one more SE than T3, T3 has one more SE than T4, and T4 has one more SE than T5. Between two successive months, the composition of the teams changes as follows.
(a) The team allotted the challenging project, gets two SE from the team which was allotted the challenging project in the previous month. In exchange. one RE is shifted from the former team to the latter team.
(b) After the above exchange, if T1 has any SE and T5 has any RE, then one SE is shifted from T1 to T5, and one RE is shifted from T5 to T1. Also, if T2 has any SE and T4 has  any RE, then one SE is shifted from T2 to T4, and one RE is shifted from T4 to T2.
Each standard project has a total of 100 credit points, while each challenging project has 200 credit points. The credit points are equally shared between the employees included in that team.

Q. The number of times in which the composition of team T2 and the number of times in which composition of team T4 remained unchanged in two successive months are.
Detailed Solution for Test: Data Tabulation & Caselets - 1 (July 24) - Question 5

Given that there are 10 SE and 11 RE In the first month, since T1 has one more SE than T2, who in turn has one more SE than T3,... till T5, the number of SEs  in T1, T2, T3, T4 and T5 must be 4, 3, 2, 1 and 0.
Also, the team that is assigned the challenging project has one more employees than the rest. Hence, the team that is assigned the challenging project will have 5 employees, while the other teams will have 4 employees.
Since T1 is assigned the challenging project in the first month, T1 will have 5 employees, and the other teams will have 4 employees each.
The following table provides the composition of the teams in the first month:

In the second month, T2 will be allotted the challenging project.
From a, two SEs will be transferred from Tl to T2. One RE is transferred from T2 to T1.
From b, one SE will be transferred from T1 to T5, one RE will be transferred from T5 to T1. Similar transfers will happen between T2 and T4.
The following table provides the number of employees in each team in the second month:

In the third month, T3 will be allotted the challenging project.
From a, two SEs will be transferred from T2 to T3. One RE is transferred from T3 to T2.
From b, one SE will be transferred from T1 to T5, one RE will be transferred from T5 to T1.
Also, one SE will be transferred from T2 to T4 and one RE will be transferred from T4 to T2.
The following table provides the number of employees in each team in the third month:

In the fourth month, T4 will be allotted the challenging project.
From a, two SEs will be transferred from T3 to T4. One RE is transferred from T4 to T3.

From b, one SE must be transferred from T1 to T5.
However, since there are no SEs in T1, this will not happen. Also, one SE must be transferred from T2 to T4 and one RE must be transferred from T4 to T2.
However, there are no REs in T4.
Hence, this transfer will not happen.
The following table provides the number of employees in each team in the fourth month: In the fifth month, T5 will be allotted the challenging project.
From a, two SEs will be transferred from T4 to T5. One RE is transferred trom T5 to T4.
From b, one SE must be transferred from T1 to T5.
However, since there are no SEs in T1, this will not happen.
Also, one SE will be transferred from T2 to T4 and one RE will be transferred from T4 to T2.
The following table provides the number of employees in each team in the fifth month.

The composition of T2 did not change once between the third and the fourth months.
The composition of T4 changed between any two successive months.
Hence, the answer is (1, 0).

Since Aneek secured 185 credits he worked in four challenging projects and one standard project. Option A: Aneek could have worked in Tl in first month an challenging project, T2 in second month (in challenging project), T3 in third month (in challenging project), T4 in fourth month (in challenging project) and fifth month (in standard project). Hence, this is possible.
Option B: Aneek could have worked in T1 in first month (in challenging project), T2 in second month (in challenging project), T4 in third month (in standard project), T4 in fourth month (in challenging project) and T5 in fifth month (in challenging project). Hence, this is possible.
Option C: Aneek could have worked in T2 in first month (in standard project), T2 in second month (in challenging project), T3 in third month (in challenging project), T4 in fourth month (in challenging project) and T5 in fifth month (in challenging project).
Hence, this is possible.
Option D: Aneek could hove worked in T1 in first month (in challenging project). He can work in Tl or T5 in the second month. In either case, he cannot work in T3 without working in T2 first. In if we assume, he worked in T3 in the first month, he could not have worked in four teams in the five months. Similarly, we can rule out the other possibilities for this option. Hence, this is the answer.

Test: Data Tabulation & Caselets - 1 (July 24) - Question 9
Save

Directions for Questions: Applicants for the doctoral programmes of Ambi Institute of Engineering (AIE) and Bambi Institute of Engineering (BIE) have to appear for a Common Entrance Test (CET). The test has three sections. Physics (P), Chemistry (C), and Maths (M). Among those appearing for CET, those at or above the 80th percentile in at least two sections, and at or above the 90th percentile overall, are selected for Advanced Entrance Test (AET) conducted by AIE. AET is used by AIE for final selection.
For the 200 condidates who are at or above the 90th percentile overall based on CET, the following are known about their performance in CET.                                            

(2017)

(a) No one is below the 80th percentile in all 3 sections.
(b) 150 are at or above the 80th percentile in exactly two sections.
(c) The number of candidates at or above the 80th percentile only in P is the same as the number of candidates at or above the 80th percentile only in C. The same is the number of candidates at or above the 80th percentile only in M.
(d) Number of candidates below 80th percentile in P. Number of candidates below 80th percentile in C. Number of candidates below 80th percentile in M = 4:2:1.
BIE uses a different process for selection. If any candidate is appearing in the AET by AIE, BIE considers their AET score for final selection provided the candidate is at or above the 80th percentile in P. Any other candidate at or above the 80th percentile in P in CET, but who is not eligible for the AET, is required to appear in a separate test to be conducted by BIE for being considered for final selection. Altogether, there are 400 candidates this year who are at or above the 80th percentile in P.

Q. What best can be concluded about the number of candidates sitting for the separate test for BIE who were at or above the 90th percentile overall in CET?
Detailed Solution for Test: Data Tabulation & Caselets - 1 (July 24) - Question 9

The number of candidates sitting for separate test far BIE who were at or above 90th percentile in CET (a) is either 3 or 10.

From 1, h = 0.
From 2, d + e + f =150
From 3, a = b = c
Since there are a total of 200 candidates,
3a + g = 200 –150 = 50
From 4, (2a + f) : (2a + e) : (2a + d) = 4 : 2 : 1 Therefore, 6a + (d + e + f) is divisible by 4 + 2 + 1 = 7. Since d + e + f =150, 6a + 150 is divisible by 7, i.e., 6a + 3 is divisible by 7.
Hence, a = 3, 10,17, . ..
Further, since 3a + g = 50,  a must be less than 17. Therefore, only two cases are possible for the value of a, i.e.. 3 or 10.
We can calculate the values of the other variables for the two cases.
a = 3 or 10
d = 18 or 10
e = 42 or 40
f = 90 or 100
g = 41 or 20
Among the candidates who are at or above 90th percentile, the candidates who are at or above 80th percentile in at least two sections are selected for AET. Hence, the candidates represented by d, e, f and g are selected for AET.
BIE will consider the candidates who are appearing (for AET and are at or above 80th percentile in P. Hence, BIE will consider the candidates represented by d, e and g, which can be 104 or 80.  BlE will conduct a separate test for the other students whoare at or above 80th percentile in P. Given that there are a total of 400 candidates at or above 80th percentile in P, and since there are 104 or 80 candidates at or above 80th percentile in P and are at or above 90th percentile overall, there must be 296 or 320 candidates at or above 80th percentile in P who scored less than 90th percentile overall.

Directions for Questions: Applicants for the doctoral programmes of Ambi Institute of Engineering (AIE) and Bambi Institute of Engineering (BIE) have to appear for a Common Entrance Test (CET). The test has three sections. Physics (P), Chemistry (C), and Maths (M). Among those appearing for CET, those at or above the 80th percentile in at least two sections, and at or above the 90th percentile overall, are selected for Advanced Entrance Test (AET) conducted by AIE. AET is used by AIE for final selection.
For the 200 condidates who are at or above the 90th percentile overall based on CET, the following are known about their performance in CET.

Any other candidate at or above the 80th percentile in P in CET, but who is not eligible for the AET, is required to appear in a separate test to be conducted by BIE for being considered for final selection. Altogether, there are 400 candidates this year who are at or above the 80th percentile in P.

Q. If the number of candidates who are at or above the 90th percentile overall and also at or above the 80th percentile in all three sections in CET is actually a multiple of 5, what is the number of candidates who are at or above the 90th percentile overall and at or above the 80th percentile in both P and M in CET?
