Work: Calculate the value of equation (500×12×0.5×12+2×400×12×(0.5×400+12))/(500×12+2×400×12) .
Question type: Mathematical calculation
Solution:
(500×12×0.5×12+2×400×12×(0.5×400+12))/(500×12+2×400×12)
=(500×12×0.5×12+2×400×12×212)/(500×12+2×400×12)
=2071200/(500×12+2×400×12)
=2071200/15600
=132.769231
Answer:(500×12×0.5×12+2×400×12×(0.5×400+12))/(500×12+2×400×12)=132.769231
