If ‘P % Q’ means that P is the father of Q,

‘P + Q’ means that P is the son of Q,

‘P ^ Q’ means that P is the sister of Q.

Which statement is true according to this relation R ^ A + N % G + U?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 1

Using the notations, the diagrammatic representation of the question is as follows:
R ^ A + N % G + U means R is the sister of A who is the son of N who is the father of G who is the son of U.
Preparing the family tree using the following symbols:

R ^ A + N % G + U
R ^ A means R is the sister of A; therefore, R is female.
A + N means A is the son of N; therefore, A is male.
N % G means N is the father of G; therefore, N is male.
G + U means G is the son of U; therefore, G is male.
Thus, we can conclude that:
R is the daughter of N
R is the sister of A and G
N is the father of R, A and G.
A and G are brothers.

In a cricket match, 11 players played for a team. The team scored such that the four middle-order players scored 45% of total runs on the scoreboard whereas the two openers scored 80% of runs scored of that of middle-order players. The three all-rounders scored 14% of the total runs scored. If the two tail-enders scored 16 runs, then find the total runs registered on the scoreboard by the team.

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 3

Runs scored by four middle-order players = 45% of total runs
Runs scored by two openers = 80% of 45% of total runs
Runs scored by three all-rounders = 14% of total runs
Runs scored by the two tail-enders = 16
Total runs = Runs scored by middle-order player + Runs scored by openers + Runs scored by all-rounder + Runs scored by tail-enders
Converting percentage into ratio:



Let the total runs be
Runs scored by openers
Total runs,



Total runs scored by the team in the match is .

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 6

An event was organized by an event management company and the entry fee per person was fixed at Rs 250/-. On average, 2 persons from each family participated in the program and there were 300 families participating in the event. 50% of the total amount received by the company from the entry fee was spent on the arrangement. What was the amount spent on the arrangement?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 6

Given:

Entry fee per person = Rs 250

Number of people participating from each family = 2

Number of families present = 300

Percentage of the received amount spent on arrangements = 50 %

Total number of people participating = 2 × 300 = 600

Total amount received = 600 × 250 = Rs 1,50,000

Amount spent on arrangements =1,50,000 × = Rs 75,000

∴ Rs 75,000 is spent on the arrangements.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 20

Six persons are sitting in a circle. A is facing B, B is to the right of E and left of C. C is to the left of D. F is to the right of A. Now D exchanges his seat with F and E with B. Who will be sitting to the left of D?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 20

  1. Determine an initial seating that satisfies all clues
    Label six seats around a circle (clockwise) as 1 through 6. Every person “faces” the center, so “to the left” means the next seat clockwise, and “to the right” means the next seat anticlockwise.

    Use the five clues together:

    • A faces B → A and B must be three seats apart (opposite each other).

    • B is to the right of E → B sits immediately anticlockwise from E.

    • B is to the left of C → B sits immediately clockwise from C.

    • C is to the left of D → C sits immediately clockwise from D.

    • F is to the right of A → F sits immediately anticlockwise from A.

    One arrangement that meets all five at once is:

    Seat 1: A Seat 2: D Seat 3: C Seat 4: B Seat 5: E Seat 6: F

    – A (1) faces B (4).
    – B (4) is immediately anticlockwise of E (5).
    – B (4) is immediately clockwise of C (3).
    – C (3) is immediately clockwise of D (2).
    – F (6) is immediately anticlockwise of A (1).

  2. Apply the two swaps

    • D swaps with F → D moves from seat 2 to seat 6; F moves from 6 to 2.

    • E swaps with B → E moves from seat 5 to seat 4; B moves from 4 to 5.

    After these exchanges, the seats become:

    Seat 1: A Seat 2: F Seat 3: C Seat 4: E Seat 5: B Seat 6: D

  3. Identify who sits to the left of D

    • D is now in seat 6.

    • To D’s left (clockwise) is seat 1, occupied by A.

Answer: A sits to the left of D.

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 21

A, B, C, D, E, F & G are sitting in a line facing the East. C is the immediate right of D. B is at an extreme end and has E as his neighbour. G is between E and F. D is sitting third from the South end. Who are the persons sitting at the extreme ends?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 21

Sitting arrangement of A, B, C, D, E, F and G.

Solution Explanation (Step-by-Step)

  1. Determine the “third from the South end” position

    • Since they are all facing East, “South end” corresponds to the bottom of the line.

    • Label positions from South to North as 1 (Southmost), 2, 3, 4, 5, 6, 7 (Northmost).

    • “D is sitting third from the South end” ⇒ D occupies position 3.

  2. Place C relative to D

    • Facing East, a person’s Right is toward the South (i.e., toward lower-numbered positions).

    • “C is the immediate right of D” ⇒ C sits immediately to D’s South ⇒ C is at position 2.

  3. Locate B and its neighbour E

    • “B is at an extreme end and has E as his neighbour.”

      • If B were at position 1 (Southmost), then E would have to be at position 2, but position 2 is already taken by C ⇒ impossibility.

      • Therefore, B must be at the other end ⇒ position 7 (Northmost), and E sits next to B ⇒ position 6.

  4. Fit G “between” E and F

    • E is at position 6. To place G between E and F in a straight line, the only open slots that straddle position 6 are 5 and 4.

    • The order must be either E–G–F (from North downward) or F–G–E, but E is fixed at 6.

    • The only way to have G sit “between” E and F is:

      • E at 6, G at 5, F at 4.

  5. Place the remaining person A

    • Positions now occupied:

      • 7 → B

      • 6 → E

      • 5 → G

      • 4 → F

      • 3 → D

      • 2 → C

    • The only position left is 1 ⇒ A goes to position 1.

  6. Identify the extreme ends

    • South end (position 1) → A

    • North end (position 7) → B

Answer
The persons sitting at the two extreme ends are A (South end) and B (North end).

UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 24

The ratio of ages of Saurabh and his father is 5 ∶ 9. Saurabh's mother is three years younger than his father, the ratio of Saurabh's age 5 years ago and his mother's age 3 years ago was 1 ∶ 2. What is the present age of his father?

Detailed Solution for UPSC CSE Prelims Paper 2 (CSAT) Mock Test - 5 - Question 24

Given:

Ratio of age of Saurabh and his father = 5 : 9

Sourabh's mother is 3 years younger than his father

Ratio of Saurabh's age 5 years ago and his mother's age 3 years ago = 1 : 2

Let the age of Saurabh and his father be 5x and 9x respectively

Age of her mother = 9x – 3

Now, Saurabh's age 5 years ago = (5x – 5) years

Age of his mother 3 years ago = (9x – 3) – 3 years

⇒ 9x – 6 years

⇒ 10x – 10 = 9x – 6

⇒ x = 4

Present age of father = (9 × 4) years

⇒ 36

∴ Present age of father is 36 years
