Reason (Question:79578.0)

Pls elaborate the answer in a better/ different way

Question:

Albert is thrice efficient as Bijoy and Cherry is twice as efficient as Bijoy. What is the ratio of number of days taken by Albert, Bijoy and Cherry, when they work individually? 

Options:
A) 2:6:3
B) 2:3:6
C) 1:2:3
D) 3:1:2
Solution:

                                        Albert: Bijoy: Cherry

Ratio of efficiency=                3   :   1   :   2

Ratio of number of days=    \(\{ \cfrac{1}{3}:\cfrac{1}{1}: \cfrac{1}{2}\}\)   

After taking the L.C.M. = \(\cfrac{2}{6}:\cfrac{6}{6}:\cfrac{3}{6}\)

\(\Rightarrow\)                               2:  6  :  3

Take LCM of 3,1,2 which comes out to be 6
Then you'll get your answer as 2,6 and 3 days
