The mathematics interest group held a test. There were 15 questions in the whole paper. It was stipulated that 8 points would be deducted for each right question and 4 points would be deducted for each wrong question. Xiaoying got 72 points in total, and she did it right______ Question

The wrong questions are: (8 × 15-72) △ 8 + 4, = (120-72) △ 12, = 48 △ 12, = 4 (DAO); he did right: 15-4 = 11 (DAO); a: he did right 11 questions. So the answer is: 11

If it's sunny, it will take 12 days for Party A and 15 days for Party B. on rainy days, the work efficiency of Party A is 40% less than that of sunny days, and that of Party B is 10% less than that of sunny days?

In sunny days, the efficiency of a is 112, in rainy days, the efficiency of a is 112 × (1-40%) = 120; in sunny days, the efficiency of B is 115, in rainy days, the efficiency of B is 115 × (1-10%) = 350

There is a boat sailing in the water. When it finds a leak, some water has accumulated inside the boat. Water enters the boat at a constant speed from the leak. If there are 10 people scouring the water, they can finish it in 12 hours. If there are 15 people scouring the water, it takes 6 hours. If it takes 2 hours, how many people do it?

Suppose that one person's one hour water washing is "1" 12 hours: 10 * 12 = 120 6 hours: 15 * 6 = 90, water inflow per hour: (120-90) / (12-6) = 5, the original water 120-12 * 5 = 60 needs to be washed out in 2 hours, and the number of people needed is 5 + 60 / 2 = 35

Asking for help: mathematics problems of primary school to junior high school
A and B go from a to B at the same time. When a runs 200 meters, B runs 2 / 5 of the whole journey; when B runs 200 meters, a runs 5 / 8 of the whole journey. Q: when the faster one of the two reaches the midpoint, how far is the other from the midpoint?

If it is the destination, set the total distance as x A / b speed = 200 / (2 / 5 x) = (5 / 8 x) / 200 〈 1 / 4 x ^ 2 = 40000x = 400, when a line is 200m, B line is (2 / 5 x) = 160m, when a line is 400m, that is, when a reaches the destination, B line is 320m, 80m away from the destination

It is understood that individual shoe stores can make profits as long as they sell shoes 20% higher than the purchase price, but the owners often price them 50% - 100% higher than the purchase price. If you are going to buy a pair of shoes with a price of 400 yuan, how much is the minimum counter-offer under the condition of ensuring the profits of the boss and not suffering losses? How much is the maximum counter-offer?

At least: 400 △ 1 + 50% × (50% - 20%), = 400 △ 1.5 × 0.3, = 80 (yuan); at most: 400 △ 1 + 100% × (100% - 20%), = 400 △ 2 × 0.8, = 160 (yuan); a: at least 80 yuan, at most 160 yuan
