• A. 12
• B. 20
• C. 16
• D. 4

Answer 1

The correct option is D

4

The following matrix will help you solve the problem.
$\begin{array}{ccccccc}\text{Game}& \text{Starting Money with}& \text{Ghosh Gives}& \text{Gets}& \text{Dealer Gets}& \text{Gives}& \text{End}\\ & \text{with Ghosh Babu}& & & & & \\ I& 0& 0& 8& 16& 0& -8\\ II& -8& 0& 10& 0& 10& 12\\ III& 12& 0& 6& 6& 0& 12\\ IV& 12& 0& 8& 16& 0& 4\end{array}$
Since he made a net gain of 4 at the end of the game, he must have started of with 100 – 4 = 96.
Hence (d)
