Two boxes of apples are 30kg. After selling 2kg in box a, the ratio of the remaining apples to the apples in box a is 2:5. Suppose box a has x and Box B has 30-x
x -2 :30-x = 2:5
5x - 10 = 60 - 2x
7x = 70
x =10
I'm very happy to answer for you, born for your dream, zff answers questions for you
If you don't understand this question, you can ask,

The two baskets of apple a and B are the same weight. Basket a sells 7kg, basket B sells 19kg, and the remaining apple a is three times of that of basket B. how many kg are there in each basket now
No equation solution

Suppose B has x kg, then a has 3x kg
According to the condition x + 19 = 3x + 7
The solution is x = 6
So now a has 18 kg, B has 6 kg
------------
If we don't use the equation, we should analyze it like this
B than a sold 19-7 = 12, now B than a less than 2 times the number of apples
So the number of apples per unit is 12 / 2 = 6
So B is now 6, a is 6 * 3 = 18

The store brought in 280 baskets of apples, two fifths more than pears. How many baskets of pears?
There's a relation, two equations (one equation,

Set X Box
x(1+0.4)=280
280/(1+0.4)
What is the relation
