27.78 % = 5/18 hota h and we have given 27.78% work done in 5 days, so complete work will be done in 18days (5/18 work 5days mai hota h toh pura kaam 18 days mai hoga) Hence, a+b can complete full work in 18 days.

@@320garimagarg Together they take 5 days to complete 27.77% (i.e. 5/18) of work. Total time they took to complete whole work is (18/5)*5 = 18 days A take k days and B take (2k-15) days for same work.

Total work (TW) = LCM of K and (2K-15) = K(2K-15)
Efficiency of A = TW/time taken by A alone = K(2K-15)/K = 2K-15
Efficiency of B = K(2K-15)/(2K-15) = K
Efficiency of A+B = 2K-15+K = 3K-15
27.77% = 5/18
Time taken by (A+B) to complete 27.77% of total work = 5 days
Then 5/18 of total work = 5 days
Time taken by (A+B) to complete total work = 18 days
Total work/efficiency of (A+B) = 18 days
K(2K-15)/3K-15 = 18
2K²-15K = 54K-270
2K²-69K+270 = 0
K = +4.5 , +30
B takes 2K-15 time ,When we put K = 4.5 then time taken by B becomes negative which is not possible..
So, only possible value of K= 30
