Hence, option B is the correct answer.

The following are the ranks in army and their increasing order is:

The correct order (junior to senior)

4) Captain

3) Major

1) Colonel

2) Brigadier

5) General

Correct order - 4, 3, 1, 2, 5

Hence, option B is the correct answer.

Hence, option D is the correct answer.

cosec(75° – q) – sec(15° + q) – tan(65° + q) + cot(25° – q)

= sec[90 – (15° + q)] – sec(15° + q) – tan(65° + q) + tan[90 – (65° + q)]

= sec(15° + q) – sec(15° + q) – tan(65° + q) + tan(65° + q)     
                                                               [since, cosec(90° -A)=sec A,cot(90° - A)=tan A]
= 0

Given expression,

Rationalize above equation,

Let the speed of the train be x

We know that

⇒ Speed = Distance/Time

Speed after accident = 80% of x = 4x/5

According to the question,

The time difference in covering 18 km due to change in speed = 55−46 = 9 min

x = 30 kmph

Therefore, original speed of the trains is 30 kmph.

• Mahayana sect is more popular in India, China, Japan, Vietnam, Korea, Singapore, Taiwan, Nepal, Tibet, Bhutan, and Mongolia.

• Hinyana sect is more popular in countries like Sri Lanka, Myanmar, Thailand, Laos, etc.

• The Mahayana deals with salvation for all; that is why, it is called a greater vehicle.

• The Hinyana deals with salvation for an individual; that is why, it is called the lesser vehicle.
