answer is 24
let the volume of bucket be v
let the speed of water flowing through a be v1,b be v2 ,c be v3
(v1+v2+v3)10=v
30*v1=v
40*v2=v
x*v3=v
{(v/30)+(v/40)+(v/x)} *10=v
by solving we get x=24

Q.19 Alok and Bhanu play the following min-max game. Given the expression N=9+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 27 18 20 Answer is: 20 can someone plzzzzzzzzz tell me how this answer is calculeted???
