9/221 ?
4C2* (3C1*3C1)/ 52C2 = 6*3*3*2/ 52*51 = 9/221

One man and six women working together can do a job in 10 days. The same job is done by two men in β¬Λp β¬β’ days and by eight women in p+5 days. By what percentage is the efficiency of a man greater than that of a woman?
(a) 300%
(b) 500%
(c) 600%
(d) 700%

mujhe bhi yaad ho gaya lekin mujhe is me ek doubt hein
In this one, we can different answers if we select 1) one black first and two whites later or 2) Two whites first and one black later. In the first case i get 32.24.18/2 = 6912 and in the second case we get 32.25.16/2 = 6400.
Whats wrong with 2nd method...?

(1/2p) + (6/8(p+5)) = 1/10 => p = 10..
