Both A and B coal yards have some coal. If it is transported from field A (2/5) and field B is transported (1/3), then field A will transport 40 tons more than field B; if it is transported from field A (1/3), field B will carry away (2/5), then field A transports 55 tons more than field B. How much more coal does Field A store than Field B?
甲、乙两个煤场都有一些煤．如果从甲场运走(2/5)，乙场运走(1/3)，则甲场比乙场要多运40吨；如果从甲场运走(1/3)，乙场运走(2/5)，则甲场比乙场要多运55吨．原来甲场比乙场多存多少煤？
