The population of bacteria culture doubles every 2 minutes.approximately how many minutes will it take for the population to grow from 1000 to 500,000 bacteria?
(A)10 (B)12 (C)14 (D)18 (E)20

Read Solution (Total 2)

1000*2=2000 >2min
2000*2=4000 >2min
4000*2=8000 >2min

256000*2=512000
so it doubled 9 times in order to reach 500,000
hence no of mind =9*2=18

2000^1,2000^2,2000^3,2000^4.......2000^9
population increases in this sequence
taking 9*2=18

Alok and Bhanu play the following min-max game. Given the expression
N = 12+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
