A can do a piece of work in 24 days. A and his friend B can do the same work in 12
days if they work toegther. How many days will B take to complete the same work if he
works alone ?
Answers
If they both work for a day they will complete,
1/12 + 1/24 = 3/24 =1/8 work in one day.
1/8th work × 8 days of this work gives one unit of work.
Always try to think of how much each can accomplish in one day and then add every individuals work for one day and then the fraction of work thats accomplished in one day × number of days to make that fraction to 1 gives the answer.
Assumption: A and B work their maximum potential on each day.
Answer:
24 days
Step-by-step explanation:
A can do a work in 24 days i.e. 1/24 days
A and B both can do the same work in 12 days i.e. 1/12 days
therefore, A can do the work in=
= 1/12 - 1/24
= 2/24 - 1/24
= 1/24 days = 24 days
so , A can do the work in 24 days
