Raj travelled from a point X straight to Y at a distance of 80 metres. He turned right and walked 50 metres, then again turned right and walked 70 metres. Finally, he turned right and walked 50 metres. How far is he from the starting point?
Detailed Explanation:
Raj's movement from point X:
80 metres straight (assume East) → position (80, 0)
Right turn, 50 metres (South) → position (80, -50)
Right turn, 70 metres (West) → position (10, -50)
Right turn, 50 metres (North) → final position (10, 0)
Distance from X: Horizontal displacement = 10 metres, Vertical displacement = 0 metres
Answer: 10 metres

D is the father of C, and since C and B have the same parents, D is the father of both C and B.
Therefore, A (mother) and D (father) are married, making A the wife of D.

There are 15 chairs in a row. Position of P is at the middle, and Q is at 12th position counting from the right. How many chairs are there between p and Q ?
Detailed Explanation:
P's position: Middle of 15 chairs = 8th position from left (using formula (15+1)/2 = 8).
Q's position: 12th from right = 4th position from left (using formula 15 - 12 + 1 = 4).
Chairs between P and Q: Positions 5, 6, and 7 lie between position 4 (Q) and position 8 (P), giving 3 chairs.
What should come in place of ? in the following series?
117, 98, 80, 64, ?, 42
Detailed Explanation:
Pattern: The series decreases with differences that increase by +1 each time.
Differences: 117 → 98 is −19, 98 → 80 is −18, 80 → 64 is −16.
Next difference: Pattern shows increments of +1, +2, +3, so next is −16 + 3 = −13.
Missing term: 64 − 13 = 51.
Verification: 51 → 42 is −9 (increase of +4 from −13), confirming the pattern.

At what time between 2 and 3 O'Clock will the hands of a clock be together?
Detailed Explanation:
Concept: Clock hands coincide when the minute hand catches up to the hour hand.
At 2:00, the hour hand is at 60° (2 × 30°/hour). The minute hand moves at 6°/minute, the hour hand at 0.5°/minute.
After t minutes: 6t = 60 + 0.5t → 5.5t = 60 → t = 120/11 = 1010/11 minutes past 2.
