New Pattern Based Caselet Data Interpretation For SBI PO, IBPS PO, IBPS Clerk 2020

Direction: Answer the following question based on the information given below.
 
Every year, a survey of 1000 people is conducted by the World Health Organization (WHO). WHO found that in the year 2005, 2006, 2007, 2008 and 2009 the percentage of people affected by malaria were 30%, 40%, 30%, 20% and 45% respectively. WHO also found that every year out of the affected people 60% were students, 10% were house-wives and 30% were drivers. The number of house-wives, students and drivers were in the ratio 20 : 11 : 9, every year.
1
In the year 2007, find the number of house-wives affected by malaria?
» Explain it
B
In the year 2007, 30% of the population was affected by malaria out of which 10% were house-wives.

∴ The number of house-wives affected by malaria in the year 2007 = 10% of 30% of 1000 = 0.1 × 0.3 × 1000 = 30  

Hence, option B is correct.
 
2
In the year 2009, find the number of drivers who were not affected by malaria?
 
» Explain it
E
The number of house-wives, students and drivers were in the ratio 20 : 11 : 9 in each year. 
 
Let the common factor be x.
 
Also, every year 1000 people were surveyed. 
 
∴ 20x + 11x + 9x = 1000
 
∴ x = 25
 
∴ The total number of house-wives, students and drivers was 500, 275 and 225 respectively.
 
Now, in the year 2009, 45% of the total population was affected by malaria.
 
45% of 1000 = 450
 
Out of the 450 affected people, 30% were drivers.
 
30% of 450 = 135
 
Hence, the numbers of drivers who were not affected by malaria in the year 2009 = 225 − 135 = 90
 
Hence, option E is correct.
 
3
What is the difference in the number of students affected and not affected by malaria in the year 2006?
» Explain it
A
Total population of students for each year = 275
 
In the year 2006, the numbers of students affected by malaria = 60% of 40% of 1000 = 0.6 × 0.4 × 1000 = 240 students
 
∴ The number of students not affected by malaria = 275 − 240 = 35
 
∴ Difference between the two = 240 − 35 = 205
 
Hence, option A is correct.
 
4
Find the ratio of the number of house-wives affected by malaria in the year 2005 to that affected by malaria in the year 2008.
» Explain it
C
The number of house-wives affected by malaria in the year 2005 = 10% of 30% of 1000 = 0.1 × 0.3 × 1000 = 30
 
The number of house-wives affected by malaria in the year 2008 = 10% of 20% of 1000 = 0.1 × 0.2 × 1000 = 20
 
The required ratio = 30 : 20 = 3 : 2
 
Hence, option C is correct.
 
5
Which year had the maximum number of students not affected by malaria?
» Explain it
D
Total number of students = 275
 
The number of students affected by malaria in the year 2005 = 60% of 30% of 1000 = 180
 
∴ The number of students not affected by malaria = 275 − 180 = 95
 
The number of students affected by malaria in the year 2006 = 60% of 40% of 1000 = 240
 
∴ The number of students not affected by malaria = 275 − 240 = 35
 
The number of students affected by malaria in the year 2007 = 60% of 30% of 1000 = 180
 
∴ The number of students not affected by malaria = 275 − 180 = 95
 
The number of students affected by malaria in the year 2008 = 60% of 20% of 1000 = 120
 
∴ The number of students not affected by malaria = 275 − 120 = 155
 
The number of students affected by malaria in the year 2009 = 60% of 45% of 1000 = 270
 
∴ The number of students not affected by malaria = 275 − 270 = 5
 
Thus, 2008 had the maximum number of students not affected by malaria. 
 
Hence, option D is correct.
