One hundred monks eat one hundred steamed buns. The big monk eats four steamed buns each. The little monk eats one steamed buns every four. How many people do you ask the big monk and the little monk?

One hundred monks eat one hundred steamed buns. The big monk eats four steamed buns each. The little monk eats one steamed buns every four. How many people do you ask the big monk and the little monk?

Let x big monks, 4x + 1 / 4 (100-x) = 100, x = 20 big monks, 20 little monks, 80 little monks. Because each big monk eats 4 and each little monk eats 1, so 4 little monks and 1 big monk eat 5 steamed bread (set as a group) 100 △ 5 = 20 groups, daheshang = 20 × 1 = 20, little monk = 2

In track and field competitions, the circle of shot put is a circle with a diameter of 2.1 meters, and the circle of discus throw is a circle with a diameter of 2.5 meters. How many square meters is the area of discus throw larger than that of shot put?

The radius of shot put circle: 2.1 △ 2 = 1.05 (m), discus throw circle: 2.5 △ 2 = 1.25 (m), area difference: 3.14 × (1.252-1.052), = 3.14 × (1.5625-1.1025), = 3.14 × 0.46, = 1.4444 (M2); a: discus throw circle area is 1.4444 M2 larger than shot put circle area

1: 5 (1) in PE class, there are three students in each line, and there are two students in the last line; there are four students in each line, and there are three students in the last line; there are five students in each line, and there is only one student in the last line?
2: Pangpang prepared a cuboid glass jar which was 7 decimeters long, 6 decimeters wide and 10 decimeters high. He poured water 5 decimeters deep into the glass jar and put the copper block into the glass jar. He found that the copper block was completely submerged. He measured that the water level in the glass jar rose by 2 decimeters. He calculated the volume of the copper block
3: A series of regular numbers are known: half, three fourths, seven tenths, seventeen twenty-four, forty-one fifty-eight So what's the sixth number in the string?

1. No matter whether there are three, four or five stations, there is only one in the last row, so the number is the least common multiple of 3, 4 and 5 plus 1. It's very simple. 61 2. It's even simpler. The area of the glass jar is 7 * 6 = 42. When the copper block is put in and the water rises by 2, the volume of the copper block is 42 * 2 = 84 cubic decimeters
