Problem Analysis

To solve this problem, we need to determine the number of rooms required to accommodate all the children in the sanatorium. We are given that there are 364 children in total, with the number of boys being 20 more than the number of girls. The girls are to be accommodated in rooms of 4, while the boys are to be accommodated in rooms of 6.

Solution

Let's solve the problem step by step:

1. Let's assume the number of girls is x. Since the number of boys is 20 more than the number of girls, the number of boys would be x + 20. 2. The total number of children is given as 364, so we can write the equation: x + (x + 20) = 364. 3. Simplifying the equation, we get: 2x + 20 = 364. 4. Subtracting 20 from both sides, we have: 2x = 344. 5. Dividing both sides by 2, we get: x = 172. 6. Therefore, the number of girls is 172, and the number of boys is 172 + 20 = 192. 7. To determine the number of rooms required, we divide the number of girls by 4 and the number of boys by 6. - Number of rooms for girls: 172 / 4 = 43 - Number of rooms for boys: 192 / 6 = 32 8. Adding the number of rooms for girls and boys, we get the total number of rooms required: 43 + 32 = 75.

Therefore, to accommodate all the children, 75 rooms would be required.

Answer

To accommodate all the children in the sanatorium, a total of 75 rooms would be required.
