Question

Direction(1-4): Read the following information carefully and answer the following questions that follow:

Mr. Sharma, a truck driver drives his truck every day. He travels a different distance by his truck on each day.

The pie chart given below shows the percentage of distance travelled on a particular day (one out of Monday to Friday) out of the total distance that he travelled in the five days (Monday-Friday) of a particular week.

Days Speed ( in km/ hr0 Monday Tuesday Wednesday Thursday Friday

------
52
------
68
------

Total distance travelled by the truck = 2000 Km

The table given below shows the average speed (in km/hr) of Mr. Sharma's truck on the five weekdays. Some of the data is missing.

If the average speed of the truck on Sunday is 25% more than the speed on Thursday while the distance travelled on Sunday is 70 km more than the distance travelled on Monday, then find the time taken (in hrs) to travel the distance on Sunday.

Answer 1

Distance travelled on Monday = 22% of 2000 = 440 km

Similarly,

Day Distance Travelled (in km) Monday Tuesday Wednesday Thursday Friday

440
520
255
340
445

Time for which Mr. Sharma travelled on Tuesday = $\frac{520}{52}=10hrs$

Time for which Mr. Sharma travelled on Thursday = $\frac{340}{68}=5hrs$

Speed of truck on Sunday = 68 × 1.25 = 85 km/hr

Distance travelled on Sunday = 440 + 70 = 510 km

Time taken to travel the distance on Sunday = $\frac{510}{85}=6hrs$
