Choose the group of letters which is different from others.
Detailed Explanation:
ORUX: O(15)→R(18)→U(21)→X(24) gives differences of +3, +3, +3
PSVX: P(16)→S(19)→V(22)→X(24) gives differences of +3, +3, +2 (last gap breaks pattern)
CFIL: C(3)→F(6)→I(9)→L(12) gives differences of +3, +3, +3
JMPS: J(10)→M(13)→P(16)→S(19) gives differences of +3, +3, +3
Three groups maintain constant +3 difference, while PSVX has +2 in final step, making it the odd one out.
Motorcycle is related to battery in the same way as Life is related to:
Detailed Explanation:
A motorcycle requires a battery as its primary source of electrical energy to start and function.
Similarly, life on Earth depends on the Sun as its fundamental source of energy for photosynthesis, warmth, and sustaining all biological processes.
Gaurav walks 20 metres towards North. He then turns left and walks 40 metres. He again turns left and walks 20 metres. Further, he moves 20 metres after turning to the right. How far is he from his original position?
Detailed Explanation:
Starting point: (0, 0)
20 m North: Position becomes (0, 20)
Turn left (West), 40 m: Position becomes (−40, 20)
Turn left (South), 20 m: Position becomes (−40, 0)
Turn right (West), 20 m: Position becomes (−60, 0)
Final displacement: 60 metres from the original position (straight-line distance along the x-axis).

If February 1, 1996, is Wednesday, what day is March 3, 1996?
Detailed Explanation:
1996 is a leap year, so February has 29 days.
From February 1 to March 3: (29 − 1) days in February + 3 days in March = 31 days.
31 days = 4 weeks + 3 days, so Wednesday + 3 days = Saturday.
If ÷ means +, − means ÷, × means −, and + means ×, then the value of:(36×4)−8×44+8×2+16÷1\(\frac{(36\times 4)-8\times 4}{4+8\times 2+16\div 1}\) is
Detailed Explanation:
Step 1 – Replace operators: ÷ becomes +, − becomes ÷, × becomes −, + becomes ×
Numerator: (36×4)−8×4 becomes (36−4)÷8−4 = 32÷8−4 = 4−4 = 0
Denominator: 4+8×2+16÷1 becomes 4×8−2×16+1 = 32−32+1 = 1
Final value: 0÷1 = 0 (Option 2)
How many triangles are there in the following figure PQRS?
Detailed Explanation:
Step 1 – Identify base triangles from diagonals: The two diagonals PR and QS intersect at point O, creating 4 base triangles: △POQ, △QOR, △ROS, △SOP.
Step 2 – Count triangles formed by vertical line through O: The vertical line through O divides the rectangle, creating 4 additional triangles by combining adjacent base segments.
Step 3 – Count triangles formed by horizontal line through O: The horizontal line through O similarly creates 4 more triangles by combining base segments.
Total count: 4 (diagonal intersections) + 4 (vertical line combinations) + 4 (horizontal line combinations) = 12 triangles.
In a certain code language COMPUTER is written as RFUVQNPC. How will MEDICINE be written in that code language?
Detailed Explanation:
Coding Pattern: Reverse the word, then shift each middle letter (excluding first and last) +1 position in the alphabet.
COMPUTER: Reverse → RETUPMOC → Keep R, shift ETUPMO (+1 each) → RFUVQNP, keep C → RFUVQNPC.
MEDICINE: Reverse → ENICIDEM → Keep E, shift NICide (+1 each: N→O, I→J, C→D, I→J, D→E, E→F) → EOJDJEF, keep M → EOJDJEFM.
What is the 14th term of the sequence 14, 10, 6, 2...?
Detailed Explanation:
Arithmetic Progression (AP): The sequence 14, 10, 6, 2... has first term a₁ = 14 and common difference d = -4.
Using the nth term formula aₙ = a₁ + (n-1)d, the 14th term a₁₄ = 14 + (14-1)(-4) = 14 + 13×(-4) = 14 - 52 = -38.
How many times do the hands of a clock coincide in a day?
Detailed Explanation:
Concept: The minute hand moves 12 times faster than the hour hand.
In a 12-hour period, the hands coincide 11 times (at 12:00, ~1:05, ~2:11, ~3:16, ~4:22, ~5:27, ~6:33, ~7:38, ~8:44, ~9:49, ~10:55).
The next coincidence at 12:00 marks the start of the next cycle, so it is not counted twice.
In a 24-hour day (two 12-hour cycles): 11 × 2 = 22 coincidences.
What should come in place of the question mark (?) in the following sequence:
Detailed Explanation:
Pattern: In each figure, the difference between upper two numbers equals the difference between lower two numbers.
First figure: Upper: 21 – 16 = 5; Lower: 15 – 10 = 5 ✓
Second figure: Upper: 10 – 7 = 3; Lower: 13 – 10 = 3 ✓
Third figure: Upper: 21 – 14 = 7; Lower: ? – 15 = 7, so ? = 22
