The fruit store brought in 25 baskets of pears and 60 baskets of apples, a total of 2625kg. If a basket of pears weighs 20kg more than apples, a basket of pears and apples each weigh more

The fruit store brought in 25 baskets of pears and 60 baskets of apples, a total of 2625kg. If a basket of pears weighs 20kg more than apples, a basket of pears and apples each weigh more

Weight of a basket of apples: (2625-20 × 25) / (25 + 60) = 25 (kg)
Weight of a basket of pears: 25 + 20 = 45 (kg)

There is a basket of fruits in the fruit shop, of which 45% are apples. After adding 16KG Yali, only 25% are apples. How many kg are there apples in this basket?
Please write down the process. It's better to talk about the train of thought,

Let the total be X
(x +16)0.25=0.45x
Apple is 9kg
I want to know what grade are you in?

There are two fruit shops a and B. fruit shop a has 800 kg, of which apples account for 1 / 4. Fruit shop B has 1 / 4 more fruits than fruit shop a, while apple shop B has more apples than Ben
There are 3 / 4 fewer fruits in the fruit shop. Which of the two fruit shops has more apples? How much more?

Jiapingguo 800x1 / 4 = 200kg
B apple 800X (1 + 1 / 4) = 1000kg
B Apple 1000x (1-3 / 4) = 250kg
So Yiduo
250-200 more = 50kg
