Explanation

The given letters are R, O, L, H.
Arranging alphabetically: H, L, O, R.

• H, L, and R are consonants.
• O is a vowel, making it the odd one.

Explanation

Given the pattern:

12 ∗ 21 = 9 = (2 - 1) × (2 + 1) = 1 × 3 = 3 doesn't fit, but (2 + 1)² = 3² = 9 fits

23 ∗ 32 = 25 = (3 - 2) × (3 + 2) = 1 × 5 = 5 doesn't fit, but (3 + 2)² = 5² = 25 fits

If the pattern is (last digit of first number + first digit of second number)²:

34 ∗ 43 = (4 + 4)² = 8² = 64 doesn't fit, but (4 + 3)² = 7² = 49 fits

Explanation

Let's analyze the pattern:

200 - 4 = 196

196 - 16 = 180

180 - 64 = 116

116 - 256 = -140

The differences are increasing in a pattern of 4, 16, 64, 256 (powers of 4).

Explanation

The price of the stamp (Rs. 3) is irrelevant to the question.

A dozen always contains 12 items.

Explanation

Let's analyze the final positions:

Car A: 20 km East + 30 km North = (20, 30)

Car B: 20 km West = (-20, 0)

Distance between Car A and Car B:

= √((20 - (-20))² + (30 - 0)²)

= √((40)² + (30)²)

= √(1600 + 900)

= √2500

= 50 km

Explanation

Let's count the number of oranges added and removed:

Oranges added:

Order 2 appears 6 times

Oranges removed:

Order 4 appears 4 times, and each time 1 orange is removed

Net oranges = Oranges added - Oranges removed

= 6 - 4

= 2

Explanation

- Akbar < Mehmood  

- Ayaz > Mehmood  

- Zubair < Ayaz  

So the order is: Akbar < Mehmood < Ayaz, and Zubair is younger than Ayaz (could be younger or older than Mehmood or Akbar, but younger than Ayaz).

Hence, Ayaz is the oldest. 

Explanation

If 1/5 of the tank is filled in 1 hour, the whole tank will be filled in:

Time = 1 / (1/5)

= 1 × 5

= 5 hours
