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 numbers of each of the three groups is same. Find the sum of jersey numbers of each group.

• A. 26
• B. 34
• C. 78
• D. can’t be determined

Answer 1

The correct option is A 26

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: $12\times \frac{13}{2}=78$. So, sum of jersey numbers of each of the groups $=\frac{78}{3}=26$
