Correct Answer: 21 days. Given 3 men or 7 women finish a work a work in 32 days And 7 men and 5 women together will finish the twice of work in?? We know that, Man * Days / Work = Constant So, 3M = 7W M/W = 7 / 3……….(1) We can say that the efficiency of Man (M) is 7 and efficiency of woman (W) is 3. Now 7 men and 5 women will perform say 2W work in x days so, (7M+5W) * x/2W = 3M *32 / W Putting values of M and W (7*7 + 5*3)x = 3*7*32*2 X = 21*32/49+15 X = 21 * 64/ 64 X = 21 Days Hence option B is correct answer.
