Production 24021

The plant has to complete the order in 40 working days. Production takes place in two workshops. In the first one, there are more workers; therefore, they would complete the order themselves in 70 working days. In the second workshop, they would complete the order in 90 days.
a) Will the order be completed on time?
b) What day will it be?

Correct answer:

t =  39.375

Step-by-step explanation:

t (1/70+1/90)=1  16t=630  t=16630=39.375  t=8315=39.375  t<40  t=39.375
