Bina and Neena together weaves one dozen sweaters in 8 days working for 10 hours per day.
Concept used:
Efficiency × time / work = constant
Calculations:
Let the time taken by them be x in order to complete the work in 5 days.
According to concept,
Efficiency × time / work = constant
So, (Nina's efficiency + bina's efficiency)× 8 × 10/12 = (Nina's efficiency + bina's efficiency)× 5 × x/12
⇒ x = 80/5 = 16 days.
Hence, The Required value is 16 days.
