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.

Find the difference between the time taken (in hrs) by the truck on Tuesday and Monday if the speed of the trucks on these days were in the ratio 13 : 11.

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 the truck on Monday = $52\times \frac{11}{13}=44km/hr$

Time taken on Monday = \dfrac{440}{44} = 10hrs\)

Required difference = 10 – 10 = 0 hrs
