Question : The following pie chart shows the number of students who failed in different subjects in an examination. Examine the chart and answer the following question. The total number of students who have failed is 350.
The number of students who failed in mathematics is less than the number of students who failed in all other subjects by:
Option 1: 190
Option 2: 256
Option 3: 95
Option 4: 161
Correct Answer: 161
Solution :
Given: Total students = 350
Students who failed in mathematics = 27%
= $\frac{27}{100}\times350$
= 94.5
Remaining students who failed in other subjects = 350 – failed in mathematics
= 350 – 94.5
= 255.5
The difference between failing in other subjects and failing in mathematics = 255.5 – 94.5
= 161
Hence, the correct answer is 161.
