Question

In a football team 12 players are divided into three groups of 4 each and are given different jersey numbers numbering from 1 to 12 in such a way that the sum of the jersey number of each of the three groups is same. Find the sum of jersey numbers of each member of the group.

• A. 26
• B. 34
• C. 78
• D. 56

Answer 1

The correct option is A 26

Soln: The question is about adding all the numbers from 1 to 12 and then dividing by 3. So, sum of numbers from 1 to 12: $12\ast \frac{13}{2}=78$. So, sum of jersey numbers of each of the group $=\frac{78}{3}=26$
