    Composite numbers are positive integers greater than 1 that are divisible by numbers other than 1 and themselves. Here are the first five composite numbers:

    1. 4: Factors: 1, 2, 4.
    2. 6: Factors: 1, 2, 3, 6.
    3. 8: Factors: 1, 2, 4, 8.
    4. 9: Factors: 1, 3, 9.
    5. 10: Factors: 1, 2, 5, 10.

    The sum of 4, 6, 8, 9, and 10 is 37.

  • If 1/4 are writers, 1/6 are readers, and 1/8 are designers participating in different contests, and there are 33 participants in the mathematics contest, then the total number of participants is:

    • 70
    • 72
    • 75
    • 99

  • 6 men, 7 women, and 5 children complete a job for 4400. If their individual wages are in the ratio of 4:3:2, the total money earned by the 5 children is:

    • 800
    • 900
    • 977
    • 990

    To determine the total money earned by the 5 children, we need to calculate their share based on the ratio of their individual wages.

    Given:
    6 men
    7 women
    5 children
    Total money earned: 4400
    Wage ratio: 4:3:2 (men:women:children)

    Total ratio 6*4 : 7*3 : 5*2 = 55

    The total ratio of the wages of the men, women, and children is 55. This means that each unit in the ratio represents 4400/55 = 80 rupees.

    The 5 children earn 5*2 = 10 units in the ratio, so they earn 10*80 = 800 rupees
