(p.12) For the full year of 2010, the Group produced a total of 115 million tonnes of clinker and 110 million tonnes of cement, representing increases of 18% and 12% respectively from those of the previous year.
(p.13) In 2010, the Group achieved an aggregate net sales volume of cement and clinker of 137 million tonnes, representing a year-on-year growth of 15.89%.
Produciton = 115 + 110 = 225 million t
但 net sales 得 137 million t
點解 production 多 net sales 咁多?
係唔係因為 137 mt 的 net sales 己扣除內部的買賣???
