Explanation

To find the correct option for the code 2098, let's reverse the logic from the given:

LAME → 3425  

L → 3  

A → 4  

M → 2  

E → 5  

COOK → 4006  

C → 4  

O → 0  

O → 0  

K → 6  

TEST → 8598  

T → 8  

E → 5  

S → 9  

T → 8  

Now decode 2098 using above logic:

- 2 → M  

- 0 → O  

- 9 → S  

- 8 → T  

So, 2098 = MOST

Correct answer: B. MOST 

Explanation

One quarter of 250 = 250 ÷ 4 = 62.5  

- One tenth of 62.5 = 62.5 ÷ 10 = 6.25  

- One fifth of 6.25 = 6.25 ÷ 5 = 1.25

Explanation

The given series is: 3/5, 5/7, 7/9, ?

We can observe the pattern:

- Numerators: 3, 5, 7, ... → increasing by 2 → next is 9

- Denominators: 5, 7, 9, ... → increasing by 2 → next is 11

Next term = 9/11

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. 

Explanation

 "Attributes" in the context of quality include characteristics, features, traits, properties, aspects, and qualities.

Attributes  صفات

Quality خصوصیت

Explanation

A matrix with all elements equal to zero is called a Zero Matrix.

Explanation

A Vernier caliper is the most suitable instrument for measuring the internal diameter of a cylinder

As it is designed with internal jaws to provide precise measurements of internal dimensions with high accuracy

For more specialized applications, an internal micrometer or a dial bore gauge can also be used for even greater precision and to check for out-of-roundness or wear. 

Explanation

Transpose of a matrix means converting rows into columns.

Given matrix A:  

[ 1   8

  9   2 ]

Transpose Aᵗ:  

[ 1   9

  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
