Honghong dad's fruit shop brought in several kilos of bananas and pears of the same weight. Due to the abnormal weather, bananas are hard to store. When they are sold, bananas are sold at a quarter lower price, pears are sold at a quarter higher price. When they are sold, the price is 1.5 yuan per kilogram per day. Would you please calculate whether the fruit shop makes a profit or a loss when it brings in these fruits? (suppose the fruits are 500, 600, 1000 kg, etc.)

Banana loses 1 / 4 * 1.5 / (1-1 / 4) = 0.5 per catty
1 / 4 * 1.5 / (1 + 1 / 4) = 0.3
It must be a loss

Urgent, ask for formula!
What's 25 over 20?

(25-20)/20=25%

2. The master processes 720 parts in 6 hours, and the apprentice processes 15% less than the master in the same time?
3. Two passenger and freight cars start from two places at the same time and travel in opposite directions. The passenger car travels 35km per hour. It is 5 / 7 of the speed of the freight car. The two cars meet after 3.5 hours. How many kilometers is the distance between the two places?
4. I have traveled 7 / 10 of the whole journey from a to B. if each branch is 90m, I can reach B in 6.5 minutes. How many meters is the distance between a and B?

1. Mr. Li took 80 yuan to buy the prize, and 5 / 8 of the money was spent on the pen. The unit price of the remaining money was 2.5 yuan for the notebook. How many copies can I buy?
(80-80 × 5 / 8) △ 2.5 = 12 copies
2. The master processes 720 parts in 6 hours, and the apprentice processes 15% less than the master in the same time?
720÷6×（1-15%）
=120×0.85
=102

（35+35÷5/7）×3.5
=84×3.5
=294 km
4. I have traveled 7 / 10 of the whole journey from a to B. if each branch is 90m, I can reach B in 6.5 minutes. How many meters is the distance between a and B?
90×6.5÷（1-7/10）
=585÷3/10
=1950 M
