Question

After Karan has got Rs. 20 in total, another player Sarabjeet joins them, with a ball which is dealt along with the previous three and distributed among all four. Four rounds after joining, Sarabjeet has exactly the same amount as Karan. What is the number on the ball that Sarabjeet brought?

• A. 6
• B. 3
• C. 2
• D. Cannot be determined uniquely.

Answer 1

The correct option is D

Cannot be determined uniquely.

Sarabjeet joined after the 3rd round. Let the integer on Sarabjeet's ball be 'n'.
Then the score sheet after Sarabjeet joined will be:

$\begin{array}{ccccc}& \text{Karan}& \text{Aman}& \text{Vijendar}& \text{Sarabjeet}\\ \text{After 3 rounds}& 20& 10& 9& 0\\ \text{4th round}& 1& 8/n& 8/n& 4\\ \text{5th round}& 1& 8/n& 8/n& 4\\ \text{6th round}& 1& 4/n& 4/n& 8\\ \text{7th round}& 1& 4/n& 4/n& 8\\ \text{Total}& 24& & & 24\end{array}$
