The total weight of the two baskets of apples is several kilograms, and the first basket accounts for 55% of the total mass. If 15 kilograms are taken out of the first basket and put into the second basket, the second basket accounts for 50% of the total mass Three fifths. How many kilos of apples are there in each basket
analysis:
After 15 kg is taken out and put into basket B, basket B accounts for 3 / 5 of the total mass, that is 60%
At this time, the armour basket accounts for 40% of the total mass
The original armour basket accounted for 55% of the total mass
Formula: total mass = 15 ÷ (55% - 40%) = 100 (kg)
Mass of a = 100 × 55% = 55 (kg)
B mass = 100-55 = 45 (kg)
There are two baskets of apples a and B, and the first basket accounts for 55% of the total weight. If 7.5kg apples are taken out of the first basket and put into the second basket, then the second basket accounts for 60% of the total weight, and the first and second baskets account for 55% of the total weight
A: 27.5kg, B: 22.5kg
It can be considered that the original weight of B accounts for 45% of the total weight, and after adding 7.5kg, it accounts for 60% of the total weight, so the total weight is 7.5kg or 60%; when the total weight is obtained, multiplying 55% is a, and 45% is B
The total weight of two baskets of apples is 109 kg. If basket a is reduced by 1 / 5 and basket B is taken away by 1 kg, the weight of the two baskets is exactly the same. How many apples are there in each basket
A (109-1) / (1 + 1-1 / 5)
=108÷1.8
=60kg
B 109-60 = 49kg
