Directions (Q. Nos. 1-5) A survey was conducted in five cities viz. Pune, Kanpur, Raisen, Surat and Trivandrum, for the percentage of people using T (trains), B (buses), C (cars) as modes of transport.Number of persons surveyed in the cities Pune, Kanpur, Raisen, Surat and Trivandrum are 2000, 4000, 6000, 3000 and 8000 respectively. Refer to the data in the triangular bar diagram to answer the questions that follow.

Question 1: The city where the least number of persons uses buses is
(a) Surat
(b) Raisen
(e) Kanpur
(d) Pune

Question 2: The average number of persons using trains for transportation in Pune, Kanpur, Raisen and Trivandrum is
(a) 1880
(b) 1750
(c) 1950
(d) None of the above

Question 3: The mode of transport used by the least number of persons in all the given cities.
(a) trains
(b) buses
(c) cars
(d) cars and buses

Question 4: Among the given five cities, the cities where less than 30% of the people use cars as transport are
(a) Kanpur and Trivandrum
(b) Pune, Kanpur and Raisen
(c) Pune and Raisen
(d) Pune, Kanpur and Surat

Question 5: Which of the following statements is not true?
(a) 50% of the people use trains for transport in Kanpur and Raisen
(b) In Trivandrum, more than 50% of the people use cars for transport
(c) More percentage of people use buses for transport in the city Surat than in the city Pune.
(d) In city Raisen, there are more percentage of people using trains for transport than buses.

3.Direction for the question: Refer the given diagram to answer the questions.

Question 1: If in 2005-06, the total project outlay increased by 20%, find the percentage increase in MP’s outlay.
(a) 50%
(b) 25%
(c) 20%
(d) 80%

Question 2: If in 2005-06, the total project outlay increased by Rs.200 crore and that of UP remained unchanged, find the total project outlay in 2005-2006, in Rs crore.
(a) 350
(b) 800
(c) 600
(d) 420

Question 3: If in 2005-06, the total project outlay of Gujarat increased by ‘x’ per cent, find the per cent increase in the total outlay.
(a) (100-4x)/5
(b) (5x-100)/4
(c) (100 – 5x)/4
(d) (4x -100)/5

Originally 4 people were scheduled for the fifth month to do coding
Therefore the cost for them (10000 × 4) = Rs. 40,000.
Now there is increase in number of men from 4 to 5 who are working on design in the fifth month.
Therefore the cost changes and the total cost for this would be (20000 × 5) =
Rs.1,00,000.
Therefore the percentage change in the in the cost incurred in the fifth month ={(100000 – 40000)/40000} x 100 = 150%
With the help of last question we will come to know that the coding stage is now
completed in 6th, 7th and 8th months. We also know that the number of people employed in the 6th month is 4 and in the 8th month is 5 and by the month 7th there are 5 people employed (from previous data). Therefore by combining all the months we find that the total cost incurred in the coding
stage = (5 + 5 + 4) × 10000 = Rs.1,40,000.
The difference in the cost will arise only because of the following months: 5, 6 and 8.
And we can compare the costs as given below.

It can be clearly seen that the difference in the cost between the old and the new technique is Rs. 60,000.

From the above table it is clear that the average cost for 5 consecutive month period is lowest for months 11 to 15.

Answer 1: (d) It can be easily observed from table that the required city is Pune. Correct option is (d)

Answer 2: (d) The total number of persons using trains for transportation in Pune, Kanpur, Raisen and Trivandrum

= 1500 + 2000 + 3000 + 1000 = 7500

The average = 7500/4 = 1875.

Correct option is (d)

Answer 3: (c) From the table, cars are used by 7000 people which is least. Hence correct option is (c)

Answer 4: (c) It is clear from the graph as well as table that in both Raisen and Pune, 12.5% of the total people use car as their mode of transport. Hence answer is option (c)

Answer 5: (b) In Trivandrum, 37.5% of the people use cars for transport. Hence option (b) is false. So the answer is option (b)
