Direction: The following questions are based on the table given below which represents the distance (in km) travelled by two persons A and B in the same direction :

1. The distance between A and B is maximum at the end of

1. As per the given above table , we see
Distance after 2 hours = 65 – 50 = 15 km
Distance after 3 hours = 100 – 70 = 30 km
Distance after 4 hours = 125 – 85 = 40 km

Correct Option: D

As per the given above table , we see
Distance after 2 hours = 65 – 50 = 15 km
Distance after 3 hours = 100 – 70 = 30 km
Distance after 4 hours = 125 – 85 = 40 km
Distance after 5 hours =160 – 110 = 50 km (maximum distance)
Thus , required answer is 5 hours .

1. What is the distance (in km) between A and B at the end of 8th hour?

1. According to given table, we have
Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A

Correct Option: B

According to given table, we have
Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A
Required distance = 210 – 185 = 25 km

1. The ratio of A’s speed during the first five hours and the last five hours is

1. From the given above table ,
Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
Total time taken = 5 hours
Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
Total time taken = 5 hours

 Required ratio = Total distance travelled in first five hours by A : Total distance travelled in last five hours by A Total time taken Total time taken

Correct Option: B

From the given above table ,
Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
Total time taken = 5 hours
Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
Total time taken = 5 hours

 Required ratio = Total distance travelled in first five hours by A : Total distance travelled in last five hours by A Total time taken Total time taken

 Required ratio of average speed = 110 : 125 = 110 : 125 = 22 : 25 5 5

1. B’s average speed (km/hour) during the first four hours is

1. On the basis of given table in question ,
Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
Total time taken = 4 hours

 B’s average speed = Total distance travelled in first four hours by B kmph Total time taken

Correct Option: C

On the basis of given table in question ,
Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
Total time taken = 4 hours

 B’s average speed = Total distance travelled in first four hours by B kmph Total time taken

 B’s average speed = 25 + 40 + 35 + 25 kmph = 31.25 kmph 4

Direction: The following table shows the productions of food- grains (in million tons) in a state for the period 1999 - 2000 to 2003 - 2004. Read the table and answer the questions.

1. The difference of average production of rice and the average production of barley over the years is (in million tonnes) :

1. According to given table, we have
Total production of Rice in given years = 270 + 420 + 350 + 400 + 560 = 2000
Number of given years = 5
Total production of barley in given years = 250 + 440 + 320 + 380 + 410 = 1800
Number of given years = 5

 Required difference = 2000 - 1800 = 400 – 360 5 5

Correct Option: D

According to given table, we have
Total production of Rice in given years = 270 + 420 + 350 + 400 + 560 = 2000
Number of given years = 5
Total production of barley in given years = 250 + 440 + 320 + 380 + 410 = 1800
Number of given years = 5

 Required difference = 2000 - 1800 = 400 – 360 5 5

Required difference = 40 million tonnes
