Answer:
12 days
Step-by-step explanation:
Let complete work be ' 1 '
( as it is in the fraction )
Work completed in one day
by A = 1/20
by B = 1/30
Together work completed in a day
=> 1/20 + 1/30
=> 3 + 2
60
=> 5/60
=> 1/12
Total time taken = 12 days

By Using Chocolate Concept,
A = 20 days
B = 30 days
LCM(20,30)= 60 (total work)
A's one day work = 60÷20 = 3
B's one day work = 60÷30 = 2
Together's one day work,
=> A+B = 3+2 =5
(No of Days = Total Work÷Efficiency)
A+B = 60÷5 = 12days
Therefore A and B together can complete the work in 12Days...
Ans:- 12days
