There are two baskets of apples. The first basket is 1.2 times of the second basket. Take 2.4 kg from the first basket to the second basket. The two baskets are equal in weight. How many kg are there in the first and second baskets?

If you take 2.4 kg from basket a to basket B, and the two baskets have the same mass, then basket a is 2.4 × 2 more than basket B, and you know that basket a is 1.2 times as much as basket B
So basket B was 2.4 × 2 △ 1.2-1 = 24 (kg)
The original number of armour basket is 24 × 1.2 = 28.8 (kg)
