Accepted Answer

Question 2

The number of products sold by the company in the year 2004 is what percent of the number of products manufactured by it in that year? (Rounded off to two digits after decimal)

Accepted Answer

Question 3

What is the ratio of the number of products not sold by the company in the year 2007 to that not sold in the year 2005?

Accepted Answer

As per given graph , Number of products not sold by the company in the year 2007 = Number of products manufactured − Number of products sold = 45 - 42.5 = 2.5 ( in thousands ) Number of products not sold by the company in the year 2005 = Number of products manufactured − Number of products sold = 37.5 - 30 = 7.5 ( in thousands ) ∵ ratio = Number of products not sold by the company in the year 2007 : Number of products not sold by the company in the year 2005 = 2.5 : 7.5 = 1 : 3

Question 4

What is the difference between the number of products manufactured by the company in the year 2009 and in 2008?

Accepted Answer

From the given graph, We can see that, Number of products manufactured in 2009 = (52.5) × 1000 Number of products manufactured in 2008 = (48) × 1000 Required Difference = Number of products manufactured in 2009 - Number of products manufactured in 2008 Required Difference = ( 52.5 − 48 ) × 1000 = 4.5 x 1000 = 4500

Question 5

Accepted Answer

Question 6

Accepted Answer

Question 7

What is the approximate average number of constructions (constructed, demolished and redeveloped) in the city R?

Accepted Answer

Average number of constructions in City R = (number of constructed building + number of demolished building + number of redeveloped building )/3 Average number of constructions in City R = 150 + 225 + 250/3 = 625/3 = 208.33 Approximate 208 %

Question 8

What is the respective ratio of the number of building demolished in city T to the number of buildings redeveloped in city P?

Accepted Answer

Required ratio = number of building demolished in City T / number of buildings redeveloped in city P Required ratio = 175 : 300 = 7 : 12

Question 9

What is the difference between the total constructions (constructed, demolished and redeveloped) in city Q and city T?

Accepted Answer

Total constructions in City Q = constructed building + demolished building + redeveloped building Total constructions in City Q = 100 + 175 + 275 = 550 Total constructions in City T = constructed building + demolished building + redeveloped building Total constructions in City T = 175 + 250 + 300 = 725 Their difference = 725 - 550 = 175

Question 10

The total number of buildings constructed across the cities is approximately what per cent of the total number of buildings redeveloped across the cities?

Accepted Answer

Total number of buildings constructed across the cities = 200 + 100 + 225 + 300 = 1100 Total number of buildings redeveloped across the cities = 300 + 275 + 250 = 1400 Required percentage = 1100 x 100 /1400 = 78.57% approx. 79%

Question 11

What is the average number of buildings demolished across the cities?

Accepted Answer

Average number of building = number of building across the cities (P + Q + R + S + T )/5 Average number of building = 50 + 175 + 150 + 75 + 175/5 = 625/5 = 125

Question 12

Expenditure of company B in years 2003 and 2004 were in the ratio of 5 : 7 respectively. What was the respective ratio of their incomes?

Accepted Answer

Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10 Hence, the required ratio = 7x : 91x/10 = 10 : 13

Question 13

Expenditure of company B in 2006 was 90% of its expenditure in 2005. Income of Company B in 2006 was what percent of its income in 2005?

Accepted Answer

Let expenditure of company B in 2005 = Rs. x; then I1(Income) = x + 35/100 x = Rs. 27x/20 Since . expenditure of company B in 2006 = 90/100 x Rs. x = Rs. 9x/10.then I2(Income ) = 9x/10 + 45/100 x 9x/10 = 9x/10 +81x/200 = Rs. 261x/200 Hence, required percentage = 261x/200/27x20 x 100 = 290/3 = 962/3%

Question 14

If the income of A in 2005 was Rs. 1,42,500 what was its expenditure in that year?

Accepted Answer

Expenditure = Income - Profit As per given graph in question, Income in 2005 = 1,42,500 Rs. Profit in 2005 = 50% Let expenditure of Company A in 2005 = Rs. E; then E + E x 50/ 100 =142500 ⇒ E + E x 1/2 =142500 ⇒ (2E + E)/2 =142500 ⇒ 3E =142500 x 2 ⇒ E =142500 x 2/ 3 ⇒ E = 47500 x 2 ⇒ E = Rs. 95000

Question 15

If the experditure of company 'A' in 2004 was Rs. 75 lakhs and income of Company A in 2004 was equal to its experditure in 2005. What was the total income (in lakhs Rs) of the company A in 2004 and 2005 together?

Accepted Answer

In 2004, expenditure of Company 'A' = Rs. 75 lakh Since, income of the company 'A' in 2004 = 75 + 25/100 x 75 = Rs. 93.75 lakhs Now, expenditure of the 'A' in 2005 = Rs. 93.75 lakhs Since, their income = 93.75 + 50/100 x 93.75 = Rs. 140.62 lakhs Hence total income for both the years = 93.75 + 140.62 = Rs. 234.37 lakhs

Question 16

Total expenditure of Companies A & B together in 2008 was Rs. 13.5 lakhs. What was the total income of the two companies (in lakh Rs.) in that year?

Accepted Answer

Here total experditure of both companies are given while their individual expenditures are needed to determine their incomes, Since their total income of the two companies can not be determined by the given datas

Question 17

Which year has the highest percent increase/decrease in exports as compared to the previous year?

Accepted Answer

As we see in the graph the Export graph is higher for 2003 to 2004 years. So we will calculate for this year. Required percentage for 2004 = (Export in 2004 - Export in 2003) x 100/Export in 2004 Required percentage for 2004 = (600 - 200) x 100/200 = 200%

Question 18

What is the maximum increase in percentage from minimum export in the given years?

Accepted Answer

Required percentage = 950 - 200/200 x 100 = 375%

Question 19

What is difference in exports in 2004 and 2005?

Accepted Answer

Required difference = Rs. (600 - 450) crores = Rs. 150 croes

Question 20

What is the total export (in crore rupees) in the given years?

Accepted Answer

Total export in given years = Rs. (300 + 200 + 600 + 450 + 600 + 800 + 950) crores = Rs. 3900 crores
