Question
10 machines can produce 25 items in 5 hours. How long will
8 machines take to produce 40 items?Solution
ATQ,
Let the efficiency of each machine be 'x' items per hour
Let the required time be 't' hours
Therefore, (10x × 5) / 25 = (8x × t) / 40
Or, t = (10x × 5 × 40) / (8x × 25) = 10
Required time = 10 hours
