Quantity:

1. A person travels 285 km in 6 hr. In the first part of the journey, he travels at 40 km/hr by bus. In the second part, he travels at 55 km/hr by train. The distance traveled by train is  

(a) 156 km   

(b) 165 km  

(c) 615 km   

(d) 561 km 

2.  A car covers four successive 6 km stretches at speeds of 25 kmph, 50 kmph, 75 kmph and 150 kmph respectively. Its average speed over this distance is  

(a) 55 kmph 

(b) 50 kmph    

(c) 75 kmph    

(d) 150 kmph  

3. The speeds of three cars are in the ratio 3 : 4 : 5. The time taken by each of the them to travel the same distance is in the ratio;  

(a) 12 : 15 : 20     

(b) 3 : 4 : 5     

(c) 20 : 15 : 12     

(d) 5 : 4 : 3

4. A certain distance is covered by a cyclist at a certain speed. If a jogger covers half the distance in double the time, the ratio of the speed of the jogger to that of the cyclist 

(a) 1 : 2    

(b) 2 : 1   

(c) 1: 4   

(d) 4 : 1 

5. Walking at 5 km/hr a student reaches his school from his house 15 minutes early and walking at 3 km/hr is late by 9 minutes. What is the distance between his school and his house?  

(a) 5 km   

(b) 8 km   

(c) 3 km   

(d) 2 km 

Answers with Explanation:

1. (b)

Let distance traveled by train be x km

so (285-x)/40 + x/55 = 6

=> x = 165 km

2. (b)

Total distance = 4*6 = 24 km

Total time = 6/25 + 6/50 + 6/75 + 6/150  = 72/150 hr.

so The average speed = total distance /total time = 24/(72/150) = (24*150)/72 = 50 km/hr.

3. (c)

4. (d)

If the time taken by cyclist to cirtain distance is t

then jogger covers half distance in 2t time

then jogger covers total distance in 4t time

then the ratio between their time = t:4t = 1:4

so The ratio between their speeds = 4:1

5. (c)

Distance = Product of speed/Difference of speeds * time difference

= (5*3)/2 * 24/60 = 3 km

Direction (1-5):  In the following questions, you have passage with 5 questions. Read the passage carefully and choose the best answer to each question out of the alternatives

      Extreme weather conditions have become such a part of life all across the world over the last decade and more, that ways and means to understand and cope with them have become an essential element of survival strategies. Heatwaves in summer, cold waves in winter and extreme rainfall when it is least expected have almost become the norm. Each of these rounds takes its own toll on lives and livelihoods even as those in other areas are forced to stand as mute spectators. This summer in India, the number of lives lost to heatwave conditions has exceeded 2,000. While shrinking winter-spans are considered by specialists as a sure sign that climate change is a reality we cannot ignore, at the other end of the spectrum, hot summers are no less debilitating. Prediction of these phenomena is itself so difficult, not for lack of effort but because of the theoretical limitations of the models being used in the calculations. Broadly speaking, there is no doubt that summer heat is worsening by the year in parts of India. This fact is reflected in some climate studies. For instance, one on climate in the subcontinent over the period from 1961 to 2010 by scientists of the India Meteorological Department based in Pune and Chennai, found that compared to the first four decades, the number of heat-wave (HW) days per season was higher during 2001-2010 in many parts of north, north-west and central India. An increase was observed in the number of severe-heat-wave (SHW) days per season in some stations, mainly in north-west India. The study also found that the frequency,persistence and area coverage of HW/SHW days were more than average in years succeeding El Niño years.

1 .According to the passage what is the meaning of the phrase  "Cope with" .
(A)riskiness
(B)unsatisfied
(C)hold up
(D)to abundant
Answer: C

2.Why the prediction of the  climate change is so difficult?
(A)lack of efforts
(B)Due to pollution into the water
