设甲筐苹果重t1,单价j1;乙筐苹果重t2,单价j2→
t1:t2=6:5 → 5t1=6t2 → t2=5t1/6
j1:j2=5:4 → 4j1=5j2 → j2=4j1/5
t1*j1+t2*j2=370
t1*j1+(5t1/6)*(4j1/5)=370
t1*j1+20t1*j1/30=370
30t1*j1/30+20t1*j1/30=370
50t1*j1/30=370
甲筐苹果的价钱是 t1*j1=370*30/50=222
乙筐苹果的价钱是 t2*j2=370-222=148
t1:t2=6:5 → 5t1=6t2 → t2=5t1/6
j1:j2=5:4 → 4j1=5j2 → j2=4j1/5
t1*j1+t2*j2=370
t1*j1+(5t1/6)*(4j1/5)=370
t1*j1+20t1*j1/30=370
30t1*j1/30+20t1*j1/30=370
50t1*j1/30=370
甲筐苹果的价钱是 t1*j1=370*30/50=222
乙筐苹果的价钱是 t2*j2=370-222=148
