1000 boys and 600 girls are examined in a test. If 40% of the boys and 35% of the girls passed, then find the percentage (approximately) of the total number of candidates who failed in the test.

Correct option is C

GIVEN:
Number of Boys = 1000
Number of Girls = 600
Percentage of boys who passed the exam = 40%
Percentage of Girls who passed the exam = 35%
FORMULA USED:
Percentage = $$\frac{value }{Total \ value}$$​× 100
SOLUTION:
According to the given conditions;
Number of boys who passed the exam = 40% of 1000
=> $$\frac{40} { 100}$$​× 1000
=> 400
Percentage of Girls who passed the exam = 35% of 600
=>$$\frac{35} { 100}$$​× 600
=> 210
Total number of students passed the exam = 400 + 210 = 610
So the total number of students = 1600
Then the total number of students who failed the exam = Total number of students - Total number of students passed the exam
=> 1600 - 610
=> 990
So, the percentage of the total number of candidates who failed the test = $$\frac{990} { 1600}$$​× 100
=> 61.88%
