Question
14 chefs can cook 21 meals in 7 hours. How much time will
10 chefs take to cook 30 meals?Solution
ATQ,
Let the efficiency of each chef be 'x' meals per hour
Let the required time be 't' hours
Therefore, (14x × 7) / 21 = (10x × t) / 30
Or, t = (14x × 7 × 30) / (10x × 21) = 14
Required time = 14 hours
