  • Question
  • 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 :


  • Options
  • A. 58
  • B. 62 *2/3
  • C. 64
  • D. 67

  • Correct Answer
  • 62 *2/3 

    Explanation

    Total number of students = 1100 + 700 = 1800.

    Number of students passed = (42% of 1100 + 30% of 700) - (462 + 210) = 672.

    Number of failues = 1800-672 = 1128.

    Percentage failure = (1128/1800 * 100 )% = 62 * 2/3 %.
