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 kmCorrect 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 .

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 ACorrect 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
- The ratio of A’s speed during the first five hours and the last five hours is

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 hoursRequired 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

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 hoursB’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

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 = 5Required 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 = 5Required difference = 2000 - 1800 = 400 – 360 5 5
Required difference = 40 million tonnes
