Answer 2

Answer: 1:2:4

Step-by-step explanation:

Concept: To ascertain the efficiency, partition the standard work hours by the genuine measure of time worked and increase by 100. The nearer the last number is to 100, the more viable your workers are. In any case, there's in every case some spread that relies upon the intricacy of the assignment.

Step 1: A can do half of a piece of work in one day whereas B can do the full work.

So $\frac{A}{B} =$$\frac{1}{2}$

Step 2: B can do half of the work as C do in one day.

So, $\frac{B}{C} = \frac{1}{2}$

Step 3: A: B: C = 1: 1*2 : 2*2 = 1:2:4

Final Ans: the ratio of the efficiencies of A , B, and C is  1:2:4.
