    Is there any other information in the question.

    Hi anime_mania,

    Is there any constraint on the ratio of number of children, ladies and men?

    Here are just some solutions, without constraints, it worked out to be more than 7 solutions.

    1. Try to fit as much males as possible
    100/3 = 33 and 1/3 , where 1 male takes 3 loaves
    => 33 men and left with 1 loaf of bread.
    1 loaf can be given to 2 children.

    Therefore, 33 men, 2 children and zero ladies

    2. Try to fit as many ladies a possible
    100/2 = 50, where 1 lady takes 2 loaves
    => 50 ladies, zero male, zero child

    3. Try to fit as all children
    100/(1/2) = 200 children, where 1 children takes half a loaf
    => 200 children, zero male, zero female

    4. Try to fit with an even distribution
    Let a group be 1 male, 1 lady and 1 children.
    Loaves of bread required for a group is 3 + 2 + 0.5 = 5.5
    100/5.5 = 18.181818....

    18 * 5.5 = 99
    => we can have 18 groups with 1 loaf of bread left (100 - 99)
    1 loaf can be distributed to 2 children

    Therefore, we can have
    18 males, 18 ladies and 20 children.

    5. From solution 4. Decrease the number of males to 17, distribute to 1 more lady and 2 children. You will have
    17 males, 19 ladies and 22 children.

    6. From solution 4. Decrease the number of male to 17, distribute all to 6 children
    17 males, 18 ladies and 26 children.

    7. From solution 4. Decrease the number of ladies to 17, distribute all to 4 children
    18 males, 17 ladies and 24 children.

    You can go on and on adjusting the number with different combination.

    For every male that you reduce (3 loaves of bread available), you can either add 1 lady (2 loaves each lady) and 2 children (1/2 loaf each child) or zero lady and 6 children (1/2 loaf each child).

    For every lady that you reduce (2 loaves of bread available), you can add 4 children (1/2 loaf each child).

    For every 2 ladies that you reduce (4 loaves of bread available), you can add 1 male (3 loaves of bread) and 2 children (1/2 loaf each child).

    You will end up with more than 7 solutions.
