Example: Data Interpretation Questions on caselets

A school has 400 students- boys and girls, who are in the ratio of 3:5. The students speak Hindi, English or both the languages. 12% of the boys speak only Hindi, 22% of the girls speak only English, 24% of the total students speak only Hindi and the number of boys speaking both the languages is six times the number of boys speaking only Hindi.

1)    How many boys speak Hindi?
2)    How many girls speak only Hindi?
3)    How many students speak English?
4)    The number of girls speaking only Hindi is what percent of the total number of students speaking only Hindi?
5)    What is the ratio of the number of boys to the number of girls speaking both the languages

Solution:
Information analysis –
Total Number of students = 400
Ratio of boys and girls; B: G = 3: 5
Number of boys = 3/8 x 400 = 150
Number of girls = 5/8 x 400 = 250
Organise the data in a systematic order. Here, we have arranged them in a form of table.

 Only Hindi Only English Both the languages Number of Boys(150) 12% of 150 = 18 150 – 18 – 108 = 24 6 x 18 = 108 Number of Girls (250) 96 – 18 = 78 22% of 250 = 55 250 – 78 – 55 = 117 Total number of students (400) 24% of 400 = 96

Question 1: How many boys speak Hindi?
Step 1:
Solution:
In this question, we need to calculate the percentage of boys who speak Hindi. It means that we need to calculate the percentage of boys who speak only Hindi and boys who speak Hindi + English.

Step 2:
Number of boys who speak only Hindi = 18
Number of boys who speak Hindi + English = 108
18 + 108 = 126

Therefore, the number of boys who speak Hindi are 126

Question 2:  How many girls speak only Hindi?
Solution:
Step 1:
In this question, we need to calculate the number of girls who speak only Hindi.
From the table above, we get to know that number of girls who speak only Hindi are 78.

Therefore, the number of girls who speak Hindi are 78.

To have an edge over data interpretation questions, practice more questions from data interpretation.
Question 3: How many students speak English?
Solution:
Step 1:
In this question, we need to calculate the number of students who speak English. So we subtract the number of students who speak only Hindi from the total number of students
Total number of students – Number of students who speak only Hindi
400 – 96 = 304

Therefore, the number of students who speak English are 304.

Question 4: The number of girls speaking only Hindi is what percent of the total number of students speaking only Hindi?
Solution:
Step 1:
Number of girls who speak Hindi – 78 [x]
Total number of students who speak only Hindi – 96 [y]
As we need to find the percentage change we know that
x/y x 100

Step 2:
78/96 x 100
81.25%

Therefore, 81.25% is the percentage change.

Question 5:  What is the ratio of the number of boys to the number of girls speaking both the languages?
Solution:
Step 1:
Number of boys speaking both the languages = 108
Number of Girls speaking both the languages = 117
The ratio of the number of boys who speak both the languages: Number of girls who speak both languages
= 108: 117

Step 2:
By further simplification we get,
12:13

Therefore, the ratio of boys is to girls who speak both the languages are 12:13.
