Q:

In a class 60% of the students pass in English and 45% pass in Hindi. If 25% of them pass in both subjects, what percentage of the students fail in both the subjects?

A) 20%	B) 25%
C) 30%	D) 15%

Answer & Explanation Answer: A) 20%

Explanation:

Percentage of students passed in English = 60%

Percentage of students passed in Hindi = 45%

Percentage of students passed in both subjects = 25%

ATQ,

Percentage of students passed in only English = 60 - 25 = 35%

Percentage of students passed in only Hindi = 45 - 25 = 20%

Therefore, Percentage of students failed = 100 - (35 + 25 + 20)

= 100 - 80 = 20%.

The ages of Sunitha and Pranitha are 40 years and 60 years, respectively. How many years before the ratio of their ages was 3 : 5?

A) 10 years	B) 15 years
C) 18 years	D) 24 years

Answer & Explanation Answer: A) 10 years

Explanation:

Given the ages of Sunitha and Pranitha are 40 years and 60 years.

Let before 'm' years, their ages be in the ratio of 3 : 5

ATQ,

$\frac{40 - m}{60 - m} = \frac{3}{5}$

=> 200 - 5m = 180 - 3m

=>2m = 20

=> m = 10 years.

Q:

Akhil after travelling 50 km meets Raju who suggests him to go slower. He then proceeds at ¾ of his former speed and arrives at his destination 35 minutes late. Had the meeting occurred 24 km further Akhil would have reached its destination 25 minutes late. What is the initial speed of Akhil?

A) 48 kmph	B) 36 kmph
C) 24 kmph	D) 20 kmph

Answer & Explanation Answer: A) 48 kmph

Explanation:

Let the initial speed of Akhil be '4p' kmph

Then speed after decrease in speed = '3p' kmph

We know that,

Change in speed == Change in time

According to the given data,

$\frac{24}{3 p} - \frac{24}{4 p} = \frac{35 - 25}{60} = > p = 12$

Hence, the initial speed of Akhil = 4p = 4 x 12 = 48 kmph.

Q:

A 200 m long train passes a motorcycler, running in the same direction at 12 km/hr, in 15 second and a jeep travelling in the same direction in 20 s. At what speed is the car travelling (length of both the motorcycler and jeep is negligible)?

A) 36 kmph	B) 32 kmph
C) 29 kmph	D) 24 kmph

Answer & Explanation Answer: D) 24 kmph

Explanation:

Let the speed of the train be 'S' kmph

From the given data,

Distance = Length of train = D = 200 mts = 200 x 18/5 kms

Time = 10 sec

given speed of the motorcycler = 12 kmph

Relative speed as they are moving in the same direction = (S - 12) kmph

$(S - 12) = \frac{200 x \frac{18}{5}}{15} S - 12 = 48 S = 60 kmph$

Hence, the speed of the train = S = 60 kmph

Now,

Let the speed of the jeep be 'x' kmph

$60 - x = \frac{200 x \frac{18}{5}}{20} 60 - x = 36 x = 60 - 36 x = 24 kmph$

Therefore, the speed of the jeep = x = 24 kmph.
