Step-by-step explanation:
Now, it is given that C takes 6 days more than A. So, days taken by c = days taken by A + 6 i.e.
c = 3/4c + 6 => 1/4c = 6 => c = 24 days
3/2c = 36 days
3/4c = 18 days
So, A,B and C will take 18, 36 and 24 days respectively to get the job done.
Let’s assume they need to make 72 pizzas (which is LCM of 24, 36 and 18). So, A will make 4 pizzas daily (72 pizzas / 18 days), B will make 2 pizzas daily (72 pizzas / 36 days) and C will make 3 pizzas daily (72 pizzas/ 24 days).
And together they can make 4 + 2 + 3 = 9 pizzas daily. Time required for them to make 72 pizzas = 72 / 9 = 8 days.
