Question

The initial money Ghosh Babu had (before the beginning of the game sessions) was Rs X. At no point did he have to borrow any money. What is the minimum possible value of X?

• A. 16
• B. 8
• C. 100
• D. 24

Answer 1

The correct option is B

8

The following matrix will help you solve the problem.
$\begin{array}{ccccccc}\text{Game}& \text{Starting Money with}& \text{Ghosh Gives}& \text{Gets}& \text{Dealer Gets}& Gives& End\\ & \text{with Ghosh Babu}& & & & & \\ I& 0& 0& 8& 16& 0& -8\\ II& -8& 0& 10& 0& 10& 12\\ III& 12& 0& 6& 6& 0& 12\\ IV& 12& 0& 8& 16& 0& 4\end{array}$
The maximum negative he goes to is - 8 after the first game. Hence, Option (b) is correct.
