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
