Instructions

Study the given graph carefully to answer the question that follow:

Number of days taken by three carpenters to finish making one piece each of four different items of furniture

Question 132

If Carpenter X, Y and Z were to make a table together, how many days would they take?

Solution

From the graph, we can infer that carpenter X will take 3 days, Carpenter Y will take 6 days and Carpenter Z will take 3 days to complete a table.

Hence, their combined capacity = (1/3 + 1/6 + 1/3)

Let n be the number of days taken by them to complete the work.

n(1/3+1/6+ 1/3) = 1

n(5/6) = 1

n = 6/5 = 1.2 days.

Hence, option E is the right answer.
