Third option: Figure : Triangle; Triangle is a type of figure but, the order is reversed.

Correct Answer: standard

Solution : The correct choice is the fourth option.

Standard means a level of quality or attainment, and is the appropriate word to fill the blank with, as it helps in correctly conveying the intended meaning that the work of the secretary is of a certain level of quality.

The meanings of the other options are as follows:

• Condition means the state of something.
• Degree means the extent or scope of an action or a condition.
• Capacity means the potential or suitability for storing or holding something.

Therefore, the correct sentence is: I'm very pleased with my new secretary. Her work is of a high standard.

Correct Answer: (2)

Solution : The correct answer is the second option.

"Where" should be replaced with "when" to convey the intended meaning that the speaker learnt about the robbery as soon as they reached the exhibition. "Hardly...when" is the correct correlative conjunction to be used in the sentence.

Therefore, the correct sentence is: "Hardly had I reached the exhibition when I learnt about the major robbery."

Correct Answer: 40 m

Solution :
Let $AB$ be the tower and $CD$ be the pole.
$CD = BE = 10$ m
In $\triangle BCE$,
$\tan$ 30° = $\frac{10}{CE}$
⇒ $\frac{1}{\sqrt3}$ = $\frac{10}{CE}$
⇒ $CE = 10\sqrt3$
In $\triangle ACE$,
$\tan$ 60° = $\frac{h}{CE}$
⇒ $\sqrt3$ = $\frac{h}{10\sqrt3}$
⇒ $h$ = 30
So, the height of tower = 30 + 10 = 40 m
Hence, the correct answer is 40 m.

Correct Answer: D, B, E, A, C

Solution : The third option is correct.

• The sentence starts with (D) to introduce the action of Nishit's thinking.
• (B) follows to specify what Nishit is thinking about, which is the terrible traffic.
• (E) comes next to provide the result of his thinking, which is that he will surely have to deal with it.
• (A) is then used to explain what he will have to deal with, which is the traffic.
• The sentence ends with (C) to provide the context, which is on his way to work.

Hence, the correct order to form a meaningful sentence is D, B, E, A, C.

Correct Answer: 47

Solution : Given:
5 ÷ 8 + 4 × 2 – 9

After interchanging + and –, and × and ÷, the equation becomes –
= 5 × 8 – 4 ÷ 2 + 9
= 5 × 8 – 2 + 9
= 40 – 2 + 9
= 47

So, 47 is the required answer. Hence, the third option is correct.
