Bar Graph and Line Graph Question 4:
The graph shows the growth curves for three independent populations (A, B, and C). The growth model for each of these populations is
N(t) = N0ert
where N(t) is the population at time t, No is the initial population and r is the per capita growth rate.
If rA, rB, rC are the intrinsic growth rates of populations A, B, and C respectively, which of these statements is true?
Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 4 Detailed Solution
Concept:
Exponential population growth
\(N(t) = N_0 e^{rt} \)
Here, \( r\) represents the intrinsic growth rate.
Explanation:
\(N(t) = N_0 e^{rt}\)
where, \(N(t)\) is the population at time t, \(N_0\) is the initial population, and r is the intrinsic growth rate.
Population A grows the fastest, showing a steep increase.
Population B grows more moderately, with a gentler curve compared to A.
Population C grows the slowest, with the flattest curve among the three.
Since the growth rate r dictates the steepness of the exponential curve, the following relationship can be
inferred based on the graph \(r_A > r_B > r_C\)
Population A has the highest growth rate \(r_A \) because its curve rises the fastest.
Population B has a slower growth rate \(r_B \) than A but faster than C.
Population C has the slowest growth rate \(r_C\) .
The correct answer is Option 4).

If the population of India in year 2007 is 1800 million, then what will be the ratio of the population in 2007 to the population in years 2003 and 2005 taken together?
Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 5 Detailed Solution
Concept used:
Population of an area is found by dividing the total quantity or amount of an entity in that area by the per capita distribution of that entity.
Calculation:
Availability of coffee in 2003 = (720 - 240) million kg
⇒Total population in 2003 = Availability of coffee/per capita availability
⇒480 million kg/0.4 kg
⇒1200 million
Now, availability in 2005 = (600 - 400) million kg
⇒200 million kg
⇒Total population in 2005 = 200 million kg/0.5 kg
⇒400 million
∴Total population in years 2003 and 2005 taken together = (1200 + 400) million
⇒1600 million
∴Required ratio = 1800:1600
⇒18:16
⇒9:8

| D | 700 | 200 |
| E | 600 | 150 |
| F | 400 | 300 |
| G | 500 | 400 |
| H | 300 | 250 |
| I | 800 | 350 |
Which of the following statement is NOT correct?
I. The profit of D, E and F is 30.63 percent of the cost price of G, H and I.
II. The ratio of total cost price to the total profit is 1 ∶ 2.
Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 8 Detailed Solution
Download Solution PDFCalculation:
Total cost price of articles D, E, and F = 700 + 600 + 400 = 1700
Total cost price of articles G, H, and I = 500 + 300 + 800 = 1600
Total profit of articles D, E, and F = 200 + 150 + 300 = 650
Total profit of articles G, H, and I = 400 + 250 + 350 = 1000
Statement I: The profit of D, E and F is 30.63 percent of the cost price of G, H and I.
Profit of D, E and F = 200 + 150 + 300 = 650
Cost price of G, H, and I = 500 + 300 + 800 = 1600
The percentage is (650/1600) × 100 = 40.625%
So, this statement is incorrect.
Statement II: The ratio of total cost price to the total profit is 1 ∶ 2.
Total cost price = 1700 + 1600 = 3300
Total profit = 650 + 1000 = 1650
The ratio of total cost price to the total profit is 3300 : 1650 = 2 : 1
So, this statement is also incorrect.
Therefore, both statements are incorrect.
The following line graph shows the vote count (in thousands) in 5 different centres – A, B, C, D and E in two different years – 2013 and 2014.
If the number of votes at center F in 2013 and 2014 were 10% and 20% more respectively than at center B in these years, then what was the total number of votes at center F in these two years together?
Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 9 Detailed Solution
Download Solution PDFSolution:
The number of votes at center B in 2013 is 18.
The number of votes at center F in 2013 is 10% more than B.
⇒ Number of votes at center F = 18 + 10% of 18 = 18 + 18 × 10 ÷ 100
⇒ Number of votes at center F = 18 + 1.8 = 19.8 (in thousands)
The number of votes at center B in 2014 is 15.
Number of votes at center F in 2014 is 20% more then B.
⇒ Number of votes at center F = 15 + 20% of 15 = 15 + 15 × 20 ÷ 100
⇒ Number of votes at center F = 15 + 3 = 18 (in thousands)
Hence, number of votes at center F together is 19800 + 18000 = 37800.

Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 12 Detailed Solution
Download Solution PDFConcept used:
Area of rectangle = Length × breadth
Area of triangle = (1/2) × Base × Height
Distance covered 'S' = Area of (V - T) graph
Calculations:
Displacement of vehicle A = Distance covered by A = Area of ΔOPL
⇒ (1/2) × OL × LP
⇒ (1/2) × OL × (LD + PD)
⇒ (1/2) × OL × (LD + LD/2)
⇒ (1/2) × OL × 3LD/2
⇒ 3/4 × OL × LD
Displacement of vehicle B = Distance covered by B = Area of rectangle OLDC
⇒ OL × LD
The ratio between the distances covered by vehicles A and B in the time interval OL
⇒ (Displacement of vehicle A)/Displacement of vehicle B
⇒ ((3/4) × OL × LD)/(OL × LD)
⇒ 3/4
∴ The ratio between the distances covered by vehicles A and B in the time interval OL is 3 ∶ 4

The graph given below indicates the changes in key policy rates made by the Central Bank several times in a year:
Which one of the following can be the most likely reason for the Central bank for such an action?
Answer (Detailed Solution Below)
Bar Graph and Line Graph Question 14 Detailed Solution
Download Solution PDFCalculations:
From July '2' to June '16' it is almost one year. In this duration repo rate and reverse repo rate is going to increase continuously Wherever CRR is fixed. This only happens to control the inflation in the market. So whenever the central bank resists the policy rate, it is a way to suck out liquidity from the system. Normally this is due to the central bank expectation of rising inflation. Hence a continuously rising repo rate indicates an anti-inflationary stance.
∴ Option 4 is correct
