The weight of the basket is 2 / 25 of the weight of the apple. After the apple is sold for 48 kg, the weight of the remaining apple is equal to 1 / 2 of the weight of the basket? I haven't learned to use two unknowns. It's better to use an equation and an X

The weight of the basket is 2 / 25 of the weight of the apple. After the apple is sold for 48 kg, the weight of the remaining apple is equal to 1 / 2 of the weight of the basket? I haven't learned to use two unknowns. It's better to use an equation and an X

Let the apple weigh x kg
2(X-48)=(2/25)X
2X-96=(2/25)X
50X-2400=2X
48X=2400
X=50kg

There is a basket of apples. The weight of the basket is 3 / 25 of the weight of the apples. After selling 40 kg, the weight of the remaining apples is just five times the weight of the basket

Apple x basket 3 / 25X
x-40=(3/25x)*5
x=100
Apple 100 kg, basket 12 kg

The number of apples in a basket ranges from 40 to 50. For example, there is one more apple for two apples and one more apple for five apples. How many apples are there in this basket

41
Between 40 and 50, 41, 43, 45, 47 and 49 are divided by 2
Between 40 and 50, 41 and 46 are divided by 5
So it's 41
