the salary given is mentioned 400 and not 4900 (Question: 113714.0 )

may be a print error. plz correct.

Question:
Two men are as efficient as 3 women who are as efficient as 4 machines. The number of men, women and machines that worked together and completed a job is in the ratio 3 : 4 : 5. They are paid a total of Rs.4900 for the job. Find the total share of women (in Rs.).
Options:
A) 1200
B) 1800
C) 1500
D) 1600
E) None of these
Solution:
Ans: (d)

Let the job done by each man, each woman and each machine be 'a' units, 'b' units and 'c' units respectively.

⇒ 2a = 3b = 4c; Let the numbers of men, women and machines who work together be 3, 4 and 5, respectively.

Job = 3a + 4b + 5c = 3(2c)+ 4(\(\cfrac{4}{3}\) c) + 5c = \(\cfrac{49}{3}\) c units.

Total share of women = \(\cfrac{\cfrac{16}{3}c}{\cfrac{49}{3}c}\)(4900) = Rs.1600.
