Divide a batch of parts equally to Party A and Party B for processing at the same time. They work for 5 days and complete 23% of this batch of parts. It is known that the efficiency ratio of Party A and Party B is 5:3. How many days will it take for Party B to complete the assigned task?
Let B's work efficiency be x, then a's work efficiency is 53x, then: 5x + 5 × 53x = 23 & nbsp; 5x + 253x = 23 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 120 (12-23 × 33 + 5) △ 120 = 14 △ 120 = 5 (days) a: it will take 5 days for B to complete the assigned task

Party A and Party B transport a batch of coal together. Party A transports 30% of the coal first, and the rest is given to Party A and Party B by 2:5. When the transportation is finished, Party B transports 30 tons of coal. How much is this ton of coal
30 / [0.7 * (5 / 7)] = 60 tons
