a) 20:21
b) 21:20
c) 15:17

2. Work & Time

Question: A, B, and C together can complete a piece of work in 20 days. B takes twice the time A and C take together, and C takes twice the time A and B take together. In how many days can B alone complete the work?

a) 40
b) 35
c) 60
d) 45

Answer: (c) 60 days

Explanation: Using the work efficiency formula, B’s individual efficiency is derived as 1/60.


3. Profit & Loss

4. Pipes & Cisterns

Question: Three pipes, A, B, and C, are attached to a container. A and B can fill it in 20 and 30 mins respectively, while C can empty it in 45 mins. If they operate alternately for one minute each (A first, then B, then C), how long will it take to fill the container?

a) 25 min
b) 35 min
c) 20 min
d) 47 min

Answer: (d) 47 min

Explanation: After analyzing the fill-empty cycle, we determine that the container gets filled in 47 minutes.

5. Ages Problem

Question:
The present age of a father is 4 times the age of his son. After 10 years, the father’s age will be 3 times the age of his son. What is the present age of the son?

Answer:
Let the present age of the son be x years.
Father’s present age = 4x.
After 10 years, the father’s age will be 4x + 10 and the son’s age will be x + 10.
According to the given condition:
4x + 10 = 3(x + 10)
Solving:
4x + 10 = 3x + 30
x = 20.
Thus, the present age of the son is 20 years.


5. Logical Reasoning – Blood Relation

Pointing to a man, a woman says, “His mother is the only daughter of my mother.” How is the woman related to the man?

A) Sister
B) Mother
C) Aunt
D) Grandmother

Answer: B) Mother

Explanation:

  • “The only daughter of my mother” → The woman herself.
  • “His mother” = The woman.
    So, she is the man’s mother.

6. Directions

A person walks 10 meters north, then 10 meters east, then 10 meters south, and finally 10 meters west. Where is he from the starting point?

A) 10 meters east
B) Back to the starting point
C) 10 meters north
D) 10 meters west

Answer: B) Back to the starting point

Explanation: The east and west movements cancel each other, and the north and south movements also cancel each other.


7. Coding-Decoding

If in a certain language, “HELLO” is written as “IFMMP”, how is “WORLD” written?

A) XPSME
B) VNSKC
C) XPQME
D) XPTME

Answer: A) XPSME

Explanation:
Each letter is shifted one step forward in the alphabet:
H → I, E → F, L → M, L → M, O → P
Similarly, WORLD → XPSME


8. Odd One Out

Find the odd one out:

A) 36
B) 64
C) 81
D) 100

Answer: C) 81

Explanation:
All numbers are perfect squares, but:

  • 36 = 626^262
  • 64 = 828^282
  • 81 = 929^292 (odd square)
  • 100 = 10210^2102
    Only 81 is an odd square.
