Explanation

 In the context of a ratio written as "a:b," the term 'a' is called the antecedent or the first term of the ratio, while 'b' is the consequent or second term. 

Antecedent: The first term or number in a ratio.

Consequent: The second term or number in a ratio. 

For example, in the ratio 5:2, the antecedent is 5, and the consequent is 2.

  8   2 ]

Explanation

66, 63, 57, 45, ?

Now check the differences between terms:

- 66 → 63  (−3)  

- 63 → 57  (−6)  

- 57 → 45  (−12)  

Pattern: −3, −6, −12, which is multiplying by 2 each time.

So, the next difference: −24

45 − 24 = 21

Explanation

5² = 5 × 5 = 25

Explanation

Step 1: Understand what 10% means  

10% means 10 out of every 100, or 10/100

Step 2: Multiply 10% by 200  

(10/100) × 200 = (1/10) × 200 = 20

Explanation

According to BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction):

2 + 3 × 4  

= 2 + 12  

= 14

Explanation

8 : 64

→ 8 × 8 = 64 → This is 8 squared (8²).

Now apply the same logic to 7:

→ 7 × 7 = 49 → This is 7 squared (7²).

So:

8 : 64 :: 7 : 49

Correct answer: 49

Explanation

If Murshid is smaller than Azhar but taller than Ahmed, then Azhar is the tallest of the three individuals.

This conclusion stems from the fact that Murshid is shorter than Azhar, implying Azhar's greater height, and Murshid is taller than Ahmed, indicating Ahmed's shorter stature compared to both Murshid and Azhar.

Therefore, Azhar emerges as the tallest among them.
