Answer:

1/3 - 1/x=1/5

Step-by-step explanation:

Let the total work be "1"

Brody Hudson Brody+Hudson

Time 3 mins x min 5 min

Efficiency 1/3 -1/x 1/5

The efficiency of Hudson is negative as he is taking out the candies out of the bowl, since efficiency of Brody + efficiency of Hudson = efficiency of both, which means,

1/3 - 1/x = 1/5....
