Question

i. 1100 boys and 700 girls are examined in a test; 42% of the boys and 30% of the girls pass. The percentage of the total who failed is :

  • 58
  • 62 *2/3
  • 64
  • 67
4
Answer and Explanation
The Correct answer is : 62 *2/3
Explanation :
Total number of students = 1100 + 700 = 1800.
Number of students passed =(42/100$\times$1100)+(30/100$\times$700) - (462 + 210) = 672.
Number of failures = (1800-672) = 1128.
Percentage failure = (1128/1800$\times$100) = (62$\times$2/3)
