Total no of bottles = 900
No.Bottles of 1/2 kg = 400 
(i) probability that randomly sold ketchup is bottle of 1/2 kg = 400 / 900 = 4/9

(ii) probability that randomly sold ketchup is atleast 200 gm bottle = 900/900 = 1

Here the atleast 200 gm,it means the bottle must not less than 200 gm , given all bottles are more than or equal to 200 gm,so the possibilities = 900.

(ii) probability that randomly sold ketchup is a bottle of 1000 gm atmost 500 gm = 600/900 = 2/3

Here a bottle of 1000 gm atmost 500 gm , it represent that the bottle should weigh greater than or equal to 500 gm
