(a) (100-4x)/5

(b) (5x-100)/4

(c) (100 – 5x)/4

(d) (4x -100)/5

**ANSWER..1**

Answer 1: b

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%

Answer 2: a

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.

Answer 3: b

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.

Answer 4: d

Answer 5: c

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

**ANSWER.2**

**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)
