Codes for truck and train cannot be found out.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Codes for truck and train cannot be found out.

Hence data in statement II is not sufficient to answer the question.

Hence option D is correct.

Delhi Police Constable Mock Test - 10 - Question 68

Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:

Which direction is Tanya facing?
Statement I: I
f Manas who is currently facing southwest (at 45° angle), turns 135° anticlockwise, he would face the same direction as Tanya.
Statement II:  If Dinesh who is currently facing northeast (at 45° angle) turns 90° clockwise, he would face the direction 180° to the direction Tanya is facing.

Detailed Solution for Delhi Police Constable Mock Test - 10 - Question 68

From Statement I: From this statement, we get the following inference:


As per the figure, Manas who is facing southwest, turns 135° anticlockwise. Thus, he will be facing East.

It is given that he would face the same direction as Tanya. Hence, Tanya will also be facing East.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II: From this statement, we get the following inference:


As per the figure, Dinesh who is facing northeast, turns 90° clockwise. Thus, he will be facing southeast. Also, southeast is 180° to the direction of Tanya. Hence, Tanya will be facing northwest.

Clearly, Statement II alone is sufficient to answer the question.

Therefore, the question can be answered using both statement I alone or statement II alone.

Hence, option C is the correct answer.

Delhi Police Constable Mock Test - 10 - Question 69

Therefore, the conclusion cannot be derived using statement II alone.
Checking both statements I and II:
Using both statements I and II, we get the following diagram:

Since some cycles are trains and no train is buses and all cars are buses, therefore, some cycles are not cars is definitely true.
Since the required conclusion can be derived by using statements I and II together.
Hence, Option D is correct.

Delhi Police Constable Mock Test - 10 - Question 76

65% of a number is more than 25% of the number by 120. What is 20% of that number?

Detailed Solution for Delhi Police Constable Mock Test - 10 - Question 76

Given:

65% of a number is more than 25% of the number by 120.

Calculations:

Let the number be x

According to question, (65x/100) - (25x/100) = 120

⇒ (65x - 25x)/100 = 120

⇒ 40x/100 = 120

⇒ x = (120 × 100)/40 = 300

But we have to find 20%, so (20/100) × 300 = 60

∴ The required number is 60.
Shortcut Trick:

65% - 25% = 120

⇒ 40% = 120

⇒ 20% = 60

∴ The required number is 60

Delhi Police Constable Mock Test - 10 - Question 87

A dog sees a cat. It estimates that the cat is 25 leaps away. The cat sees the dog and starts running with the dog in hot pursuit. If in every minute, the dog makes 5 leaps and the cat makes 6 leaps and one leap of the dog is equal to 2 leaps of the cat. Find the time in which the cat is caught by the dog (assume an open field with no trees).
