Two boxes of apples, 176 kg in total. Take 30 kg out of box a and put it into box B. the weight of Box B is three times that of box a

Two boxes of apples, 176 kg in total. Take 30 kg out of box a and put it into box B. the weight of Box B is three times that of box a

Let a be x and B be y
x+y=176
3(x-30)=y+30
x=74 y=102
A 74kg
B 102 kg

There are two baskets of apples, a and B. the weight of the apple in a frame is 20 kg. If you take a quarter of it out of B frame and put it in a frame, the two baskets will be the same weight
Kilogram?

The original weight of frame B is 20 (1-1 / 4 × 2) = 40 kg

There are two baskets of 320 kg apples in a and B, 80% of which are taken out by a and 3 / 4 by B. at this time, there are 70 kg apples in a and B. how many apples are there?

If a is originally x kg, B is 320-x kg
X-80%X+(320-X)*(1-3/4)=70
0.2X+80-0.25X=70
0.05X=10
X=200
320-200 = 120 kg
A 200 kg, B 120 kg
