Thanks for your reply.
I have read the link attached above. You always create common denominator. However, This is not clear for me how the denominatr is the same. I copied first step from the other post.
Step 1: Plot the 3 averages on a number line, with the average apple cost (40) and the average orange cost (60) on the ends and the average cost of all the fruit (56) in the middle.
A(40)--------------------56-------O(60)
I hope you clear my confusion.
Thanks
Alligation does not require that the values in the number line be over a common denominator.
In some of my solutions -- for example, my second post at
https://www.beatthegmat.com/alligation-t283497.html -- I put the fractions over a common denominator to make the math easier.
But this step is not required.
Here, alligation can be performed directly with the given averages.
