A jar contains 180 lit. sprit. if we remove 60 lit. per day from this jar and add same amount of water then after 3 days how much sprit left in the jat?

• total vol of sprit is 180....n we remove 60 litres per day..it means 1/3rd removed and 2/3 rd remains in jar...after 3 days..
  vol of sprit remains after 3 days is 180* (2/3)*(2/3)*(2/3)=53.33 litres

• amt left after n times of replacement is=original*(1-fraction removed)^n,where n is the no of times soln been replaced
  soln:180*(1-(60/180))^3=53.33
