Twenty women can complete a task in sixteen days. In fifteen days, sixteen guys may finish the same job. What is the ratio of a man's and a woman's capacity?
A. 3 : 4 B. 4 : 3 C. 5 : 3 D. Data inadequate
Explanation: Women may finish the job in one day (20 x 16).1 day's work for 1 lady = 1/320.The task may be completed in one day by 16 × 15 guys.1 day's work for 1 guy Equals 1/240.As a result, the necessary ratio is 1/240 : 1/320.4 : 3 = 1/3 : 1/4 (cross multiplied).
