A cement plant plans to produce a batch of cement in January. In fact, it completed one third of the plan in the first ten days, 40% in the middle ten days, and another 26000 in the last ten days How many tons of cement is planned to be produced in January!
Planned production of cement
2.6÷(1+1/6-1/3-40%)
=2.6÷(1+5/30-10/30-12/30)
=2.6÷13/30
=60000 tons
