If each child is divided into five, the last child will get to three and ask how many children have and how many apples

Profit and loss
Children have
(14 + 5-3) / (5-3) = 8
Apple has
3 × 18 + 14 = 68

The kindergarten gives the children three times as many apples as the peach. The teacher gives the children five apples and two peaches. When the peach is divided, there are 20 apples left. How many apples are there

Suppose there are x peaches, then there are 3x apples. Because each child is divided into two peaches, the number of children is x / 2. And because each child is divided into five apples, when the peach is divided, the number of apples is 5x / 2, so there are 3x-5x / 2 = 20, which is reduced to X / 2 = 20, so x = 40. In other words, there are 40 peaches, then there are 120 apples

For a box of chocolates, there are still 4 chocolates with 7 chocolates, 3 chocolates with 5 chocolates and 3 chocolates. How many chocolates are there?

In other words, the number of 7 grains is 3 less
And the number of 5-grain-5-grain plots is 3 less
Therefore, the total number of grains is the common multiple of 7 and 5, which is less than 3, while the number of 3 grains and 3 fields is just the same, indicating that the total number of grains is a multiple of 3
The least common multiple of 7 and 5 is 35, 35-3 = 32, but 32 is not a multiple of 3
So add the least common multiple of 7 and 5 in turn until the requirement of multiple of 3 is met
32+35*2=102
102 is a multiple of three
So there's at least 102

If each child is divided into five, the last child will get to three and ask how many children have and how many apples
