(Foundation Section Previous Year Questions)

Q1) There are five rods K, L, M, N and O. The weight of O is twice the weight of L. The weight of L is equal to the weight of K and M taken together. The weight of M is twice the weight of K. The weight of N is thrice the weight of M. If the weight of N is 90 kg. What will be the weight of O?
A. 105 kg

B. 60 kg

C. 120 kg

D. 90 kg

Explanation: N = 90

N is thrice the weight of M

3M = N

M = 30

M is twice of K

M = 2K

K = 15

L = K+M = 45

O is twice of L

O = 2L = 90

Q2) Which is the wrong term in the following series? CMQ, FPT, JTX, OYC, UFI

A. FPT

B. OYC

C. JTX

D. UFI

Explanation: The incorrect term in the series is UFI. (Option D)

The first two terms, CMQ and FPT.

The alphabets between C and F are 2 (D, E).

The alphabets between M and P are 2 (N, O).

The alphabets between Q and T are 2 (R, S).

Now the second and third terms, FPT and JTX.

The alphabets between F and J are 3 (G, H, I).

The alphabets between P and T are 3 (Q, R, S).

The alphabets between T and X are 3 (U, V, W).

Similarly, third and fourth terms, JTX, and OYC.

The alphabets between J and O are 4 (K, L, M, N).

The alphabets between T and Y are 4 (U, V, W, X).

The alphabets between X and C are 4 (Y, Z, A, B).

By comparing the last two terms, OYC and UFI, we found that,

The alphabets between O and U are 5 (P, Q, R, S, T).

The alphabets between Y and F were found to be 6 which does not satisfy the series.

Q3) In a certain code,

A % B means 'A is the brother of B',

A & B means 'A is the mother of B',

A @ B means 'A is the daughter of B',

A \$ B means 'A is the father of B' and A # B means 'A is the sister of B'.

If K \$ Z % U & H # N @ T, how is T related to U?

A. Sister

B. Husband

C. Wife

D. Brother

Explanation: K \$ Z % U & H # N @ T

K is father of Z, Z is brother of U, U is mother of H, H is sister of N, N is daughter of T

U is mother of H& N, T is father of N

Hence T is husband of U.

Q4) Five teachers P, Q, R, S and T teach a group of students in sequence between 9 and 2 pm. Each teacher teaches for one hour. Q takes the first class. S teaches just after T, R teaches before P and T. Who takes the second class from 10 am to 11 am?

A. S

B. R

C. P

D. T

Explanation: Q takes first class from 9.00 a.m. to 10 a.m.

S teaches just after T.

R teaches before P and T.

It means R teaches before P, T and S.

Hence sequence in which the teachers take class is as follows:

Q → R → P → T → S.

Hence R will be second to take class from 10 a.m. to 11 a.m.

A. 80% and 56%

B. 95% and 53%

C. 80% and 49%

D. 80% and 51%

Explanation: Given: Students who have opted for marketing = 95%

Students who have opted for Finance = 80%

Students who have opted for Operations = 84%

Students who have opted for Human Resources = 90%

To Find: The maximum and minimum percentage of people who have chosen all of the four

Concept/Formula used: By using Venn Diagrams

Maximum percentage of people who have chosen all of the four = 80%

People opting finance is 80%, it comprises the smallest percentage of the total available for the overlap of students studying other subjects.

Minimum percentage of people who have chosen all of the four

= 100% - Max number of students studying 3 subjects or less

= 100% - (100%- 95%) – (100%-80%) – (100%-84%) – (100%-90%)

= 49%

The maximum and minimum percentage of people who have chosen all of the four are80% and 49%

Directiob Q5) - Q7) 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 T 5 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.

Q5) The number of times in which the composition of team T 2 and the number of times in which composition of team T 4 remained unchanged in two successive months are:???????

A. (2, 1)

B. (1, 0)

C. (0, 0)

D. (1, 1)

Explanation: Number of Special Skilled Employees (SE) = 10
Number of Regular Skilled Employees (RE) = 11

The composition of T2 remains unchanged in T2 in 3rd and 4th months. The composition for T4 changes constantly.
Option (B)

Q6) The number of SE in T1 and T5 for the projects in the third month are, respectively:

A. (0, 2)

B. (0, 3)

C. (1, 2)

D. (1, 3)

Explanation:

Number of SE in T1 in third month = 0
Number of SE in T5 in third month = 2
Option (A)

Q7) Which of the following CANNOT be the total credit points earned by any employee from the projects?

A. 140

B. 150

C. 170

D. 200

Explanation:

Money one person earns in a Challenging Project = 200/5 = 40
Money one person earns in a Standard Project = 100/4 = 25
An employee can earn 140 when they work in one Challenging project and 4 Standard Projects = 40 + 25*4 = 140
An employee can earn 170 when they work in 3 Challenging Projects and 2 Standard Projects = 3*40 + 2*25 = 170
An employee can earn 200 when they work in 5 Challenging Projects = 5*40 = 200
So, option (B) does not seem possible

Q8) Direction: In each of the following questions among the four answer figures which one can be formed from the cut out pieces given below????????

A. 1

B. 2

C. 3

D. 4

Explanation: The only figure that can be formed from the cut-out pieces is 2, which is option B.

Q9) Directions: In each question three statements followed by two conclusions numbered I and II have been given. You have to take the given statement to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the given statements. Give answer.

Statements :

0% frocks are pants.

All shorts are frocks.

A few jackets are pants.

Conclusions :

I. Not a single pant is short.

II. A good number of jackets are not frocks.

A. If only conclusion I follows.

B. If only conclusion II follows.

C. If neither conclusion I nor II follows.

D. If both conclusion I and II follows.

E. If either conclusion I or II follows.

Explanation: Checking C1: Not a single pant is short.

Using S2 and S1,

All shorts are frocks + '0% frocks are pants' or 'No frocks are pants' = No shorts are pants or No pants are shorts which is same as 'Not a single pant is short'. Hence, C1 follows.

Checking C2: A good number of jackets are not frocks.

A few jackets are pants + Converse of S1 (which is 'No pants are frocks) = 'A few jackets are not frocks' which is same as 'A good number of jackets are not frocks'.

Hence, C2 follows as well. Clearly, option D is the correct answer.
