A garrison of 2200 men is provisioned for 16 weeks at the rate of 45gm per day per man.How many men must leave the garrison so that the provisions may last 24 weeks at 33 gm per day per man.
I have got the answer but took me long. So, looking for better approach

OA is 200

(24*33) / (16*45) =1.1

2200/1.1 =2000

2200-2000=200

2200 * 16*45 = x*24*33

x=2000

Difference = 2200- 2000 = 200
