Let the initial height of the candles be equal to 1 unit. If the candles have burned for x hours for the first candle to be half the height of the second candle, we can write

(x/4)=((4-x)/4)


(x/6)=((6-x)/6)

Height of the first candle left = (1/2)Height of the second candle


((4-x)/4)=((6-x)/6)

x=1 hr

so ramesh light the candles before=total length of thin candle-remaining length of thin candle)=4-1=3hr

then u get t as 2Hrs

Answer / palaniappan

Alok and Bhanu play the following min-max game. Given the expression N=40+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
