6 men and 8 women can complete a work in 10 days. 26 men and 48 women can finish the same work in 2 days. 15 men and 20 women can do the same work in - days.	Select the correct option.
A) 4 days  B) 6 days  C) 2 days  D) 8 days  E) 10 days
Explanation :   Let work done by 1 man in 1 day = m and work done by 1 woman in 1 day = b   Work done by 6 men and 8 women in 1 day = 1/10   =&gt; 6m + 8b = 1/10   =&gt; 60m + 80b = 1 --- (1)   Work done by 26 men and 48 women in 1 day = 1/2   =&gt; 26m + 48b = Â½   =&gt; 52m + 96b = 1--- (2)   Solving equation 1 and equation 2. We get m = 1/100 and b = 1/200   Work done by 15 men and 20 women in 1 day   = 15/100 + 20/200 =1/4   =&gt; Time taken by 15 men and 20 women in doing the work = 4 days   4 daysnswer IS 4 days
