I really can't solve this problem. I am having problem in approach.
Every time I see work problems I am stuck in approach.
In this question, I was approaching like
14∗4∗414∗4∗4
calculating the cakes baked by 1 cook in 1 hour. I don't even know if I am right.
but now I am stuck can anyone help me.
Use the following equation:
(workers)(time) / output = (workers)(time) / output
In the equation above:
Workers and time are INVERSELY PROPORTIONAL.
As the number of workers
increases, the amount of time required to produce the same output
decreases.
Workers and output are DIRECTLY PROPORTIONAL.
As the number of workers
increases, the amount of output also
increases.
Time and output are also DIRECTLY PROPORTIONAL.
As the amount of time
increases, the amount of output also
increases.
In the problem above:
(4 cooks)(4 hours) / (4 cakes) = (8 cooks)(x hours) / (8 cakes)
4 = x.
The correct answer is
4 hours.
