B will take 40 days to do the work alone. The trick is if A takes one sixth time to do half of the work then for the rest half A will need more one sixth time. Adding both we get that A completes the work in one third time of B. Thus efficiency ratio of A:B is 3:1 that is 4 units together for 10 days = 40 units. B with an efficiency of 1 unit will take 40 days to complete the work.
Sir, 60% more efficient wale m agar hum 60/8 ko simplify nhi krte hao toh hmara answer wahi se dikh rha tha, khne ka mtlb apne 60/8 ko 25/2 likha hai jisse thoda solving time jyada lga hai! Jisse hum bcha skte hai, 60/8 and 12 ka lcm lo direct answer nikal jayga itna solve krne ki jrrurat nhi thi.
