Thicker candle last 6 hours smaller one 4. Both candles are
same length when started now thicker one is twice as large
as smaller one. Thicker candle will still have 2 hours
left of burning when smaller one is done. 6-4=2. At 5
hours for thicker candle their would be 3 hours left for
thinner candle. At 4 hours left for thicker candle thinner
candle has 2 hours left. At 3 hours left for thicker
candle thinner one has 1 hour left. At 2 hours left for
thicker canldle thinner one would be done. Therefore one
would conclude that at 4 hours for thicker candle leaves 2
hours for thinner one. Thicker candle has 6 hours so 6-2=4
and thinner 4-2=2 and 2 is 1/2 of 4 so answer is 2 hours.

Alok and Bhanu play the following min-max game. Given the expression N = X - Y – Z where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be • 4 • -18 • 9 • 2
