The average speed in first hour = 10 km/hr

Average speed represented by the graph

$= \frac{10 + 20 + 30 + 50 + 60 + 60 + 65 + 60 + 45 + 30}{10}$

$= \frac{430}{10} = 43 k m / h$

Direction for question 1 to 4: refer to the following table and solve the questions based on it.

The following charts show the sector wise percentage break-up of $ 650 billion, which is the GDP of the country with a population of 12 billion people. 70 percent of the population of the country constitutes its working population, engaged in the various sectors of the economy and contribution to the GDP.

Productivity is defined as the average amount contributed to the GDP per person in that group or sector.

In the next year, the work force engaged in each of the sectors maintains its productivity at the same level. If there is an increa

Population = 12 billion = > working population = 0.7 * 12 = 8.4 billion.

	Contribution to GDP ($ billion)	Number of People (billion)	Productivity ($/Person)
Agriculture	= 0.27 of 650 = 175.5	= (22/36) of 8.4 = 5.13	34.2
Manufacturing	= 0.22 of 650 = 143	= (9/36) of 8.4 = 2.1	68.1
Services	= 0.51 of 650 = 331.5	= (5/36) of 8.4 = 8.4	284.1
Working population	650	= 0.7 of 12 = 8.4	77.4
Total population	650	12	54.2

Since we do not know anything about the non-working population, we cannot determine the answer.

The regular mathematics faculty could not teach because of being sick. As a stop gap arrangement different visiting faculty taught different topics on 4 different days in a week. The scheduled time for class was 7:00 am with maximum permissible delay of 20 minutes. The monsoon made the city bus schedules erratic and therefore the classes started on different times on different days.

Mr. Singh didn't teach on Thursday. Calculus was taught in the class that started at 7:20 am. Mr. Chatterjee took the class on Wednesday, but he didn't teach probability. The class on Monday started at 7:00 am, but Mr. Singh didn't teach it. Mr. Dutta didn'

Non-working population contributes nothing to the GDP; hence, its productivity is zero.
