The weight of a oil barrel is 1.5 times that of B oil barrel. If 2.5kg is taken out of a oil barrel and put into B oil barrel, then the weight of a and B oil barrels is equal How many kilos each I know the answer, the clearer the better!

The weight of a oil barrel is 1.5 times that of B oil barrel. If 2.5kg is taken out of a oil barrel and put into B oil barrel, then the weight of a and B oil barrels is equal How many kilos each I know the answer, the clearer the better!

Let B have X, then a is 1.5x
1.5x-2.5＝x+2.5
0.5x=2.5+2.5=5
x=10
So it turns out that a is 15 kg and B is 10 kg

There are two barrels of oil a and B. the weight of barrel a is 1.8 times that of barrel B. If 12 kg oil is taken from barrel a and put into barrel B, the weight of the two barrels will be equal
How many kilos did two barrels of oil weigh?

B barrel 12 × 2 △ 1.8-1 = 24 △ 0.8 = 30 kg
A barrel 30 × 1.8 = 54 kg

The mass of water in barrel a is 1.5 times that of water in barrel B. If 2.5 kg of water is taken from barrel a and put into barrel B, the mass of water in barrel a and barrel B is equal. How many kg of water were there in barrel a and barrel B?

2.5 × 2 ^ (1.5-1) = 5 ^ 0.5 = 10 (kg) 10 × 1.5 = 15 (kg) a: there was 15 kg of water in bucket A and 10 kg in bucket B

Pile a weighs 60 kg, and pile B weighs 12 kg less than pile a

(60 + 60-12) △ 2 = 54kg
（60-54）÷60=10%
