bunch of apples were originally planned to be put into two baskets of A and B according to the ratio of 5:4. The actual basket A contains 27 kilograms of apples, which is less than the original weight (1/4). How many kilograms of apples were originally planned to be contained in basket B? (converting unit "1" and backcasting)
一堆苹果原计划按5：4分别装入甲、乙两筐里．实际甲筐装苹果27千克，比原分配的重量少(1/4)，原计划乙筐装苹果多少千克？(转化单位"1"和倒推法)
