Video Summary

The box contains 36 cookies. The cookies must be fewer than 50 and divisible evenly between 2, 3, and 4 children. Thus, they must be a multiple of 12, as 12 is the least common multiple of 3 and 4. Possible numbers are 12, 24, 36, and 48. Additionally, when 6 is added, the total should be divisible by 7. By checking these conditions, 36 is the only number that, when 6 is added, becomes 42, which is divisible by 7. Therefore, the correct number of cookies in the box is 36.
