Among = Used for more than two persons or things, i. e. at least for three persons / things or more
Example: The money is to be / divided between Sukhi Ram, / Samridhhi Kumari and Vaibhav Prakash.
Explanation: Here, the number of persons getting the money is three (more than two) . So, there is an error in the second part of the sentence and ‘among’ should be used in place of ‘between’.
So, the correct sentence should be:
The money is to be divided among Sukhi Ram, Samridhhi Kumari and Vaibhav Prakash.
