Answer / sudheer
first consider downwards: jill comes in 1hr and jack in 3hr. so x is 2hr.
now upwards:let speed of jack be '2p' then speed of jill is 'p'.
now (3/p)-(3/2p)=2 and hence jack speed is 2p= 1.5km/hr.

Answer / guest
Total Journey is 6km, so 3km upwords and 3km Downwords.
Getting Down:
Jill speed is 3kmph. So, he takes an Hour to get down.
Jack speed is 1kmph. So, he takes 3 hours to get down.
So x=2 hrs.
Climbing the hill:
Jack waiting time is x ie, 2 hrs.
So Jack went to top of the hill in 3hrs and Jill in 1hr.

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
a(3,6,9) b(5,7,8,) c(7,8,9,) which is greater
