1316 , I am gonna kill it :sneaky:

P.S. Anyone knows any other approach to the bacteria question other than the one given in the key ?



Hi,

I solved it as follwoing:
let 100 be starting bacteria.

then after 2nd hour no. is number is reduced to 50.
Its given after second hour bacteria == sum till infinity (==half at starting, deduced)
So applying GP concept series goes like this:
100, 100x,100x^2...
Simply we get the common ration as (1/2)^1/2
series is 100,100/(2)^1/2,50, 50/(2)^1/2.
Third term is 50/(2)^1/2 == 35.something. option D =35.36 :grin::biggrin:
