Let the numerator = x and denominator = y

y + 3 = 2y ⇒ y = 3

x +1= 3 ⇒ x = 2

∴ xy = 2 × 3 = 6

r% of r = 49
r² = 49 × 100
r = 7 × 10 = 70
Hence, Option B is correct.

Let AB be the tower and let C and D be the two's positions men.
At that point ∠ACB = 30°,∠ADB = 45°and AB = 50 m
AC/AB = Cot30° = √3 => AC/50 = √3
=> AC = 50√3m
AD/AB = cot 45° = 1 => AD/50 = 1
=> AD = 50M.
Separation between the two men = CD = (AC + AD)
= (50√3 + 50) m = 50(√3 + 1)
=50(1.73 + 1)m = (50 * 2.73)m = 136.5m.

a(18) – a(14) = 32
a(n) = a + (n – 1) x d
a + (17) x d – (a + 13 x d) = 32
(17) x d – (13) x d = 32
(4) x d = 32
d = 8

Hence, "Printer" is the correct answer.

Decoding the information, 

Given:

14 ÷ 2 + 8 × 5

After replacing the signs from left to right and using the BODMAS rule,

14 + 2 × 8 - 5

= 14 + 16 - 5

= 30 - 5

= 25

Hence, “25” is the correct answer.

For this question, we will use the given table-

The relation of NZ : MA  is given below-

Similarly,

We will apply the same relation to TV : ? as-

Hence, Option (3) is correct.

Given:

Man rows 24 km in upstream and 40 km in downstream and takes 8 hours in each

Formula used:

Speed = Distance/Time

y = ½ (u - v); where, u is speed of rowing downstream, v is speed of rowing upstream and y is speed of stream

Calculation:

Downstream speed = u = 40/8 = 5 kmph

Upstream speed = v = 24/8 = 3 kmph

Thus, speed of current/stream = y = ½ (u - v) = ½ (5 - 3) = 1 kmph 

The logic followed here is:

In figure 1:

32 = (2 + 2) × 8

4 × 8

32

In figure 2:

24 = (3 + 1) × 6

4 × 6

24

Similarly,

In figure 3:

45 = (4 + ?) × 5 

4 + ? = 9

? = 9 - 4

? = 5

Hence, the correct answer is "5".

The fact that ‘domestic cats defend their territories’ holds the context of the sentence. In this regard, only the word ‘territorial’ fits in the blank correctly.
This eliminates all other options.
Meanings of the given words:
Territorial (adjective): relating to the ownership of an area.
Timid (adjective): showing a lack of courage or confidence; easily frightened.
Social (adjective): relating to society or its organization.
So, the correct option is C. 

Let us first learn the meanings of the given words:

Crucially (adverb): with decisive or vital importance.

Significant (adjective): sufficiently great or important to be worthy of attention.

Petty (adjective): of little importance.

The sentence implies that a large portion of the hospital bills was out of insurance coverage, thus ‘petty’ is contradictory. The use of ‘crucially’ is grammatically inapt as we need an adjective to qualify noun ‘portion’. The use of ‘obvious’ is contextually weak. Only ‘significant’ fits the blank grammatically and contextually.

Hence, option C is correct.

Devious: behaving in a dishonesty way
Nefarious: criminal
Surreptitious: stealthily done : secretly done
Villainous: very evil and unpleasant

Protagonist means the leading character or one of the major characters in a play, film, novel, etc

Trivial means of little value or importance
Some of the synonyms are unimportant, insignificant, inconsequential, minor
What may seem trivial to you may turn out to be inspiring and helpful to others
Even today, when adding video to a phone is a trivial cost, consumers may rebel

As per the given above sentence is given in Passive Voice.
Use structure “auxiliary + past participle”
Grass is not eaten by a lion, however hungry he may be.
Hence , option A will be correct answer .

Material consisting of text and numbers is best represented as a table slide.
