Q. THE CONTENTS IN BEAKERS A AND B ARE 90 LITRES OF MILK AND 90 LITRES OF WATER RESPECTIVELY. NOW 30 LITRES OF MILK IS TAKEN FROM A AND PUT INTO BEAKER B. AFTER THROUGH MIXING, 12 LITRES OF THE MIXTURE IS TAKEN FROM B AND PUT INTO BEAKER A. WHAT IS THE PERCENTAGE OF WATER IN BEAKER A?

• 14.28%
  After taking 30 liter of milk from A to B,Water:Milk ratio in B =90:30=3:1
  12 liters Mixture of B contains Qty. of Water:Milk=12*(3/4) :12*(1/4)=9:3 liters
  After Mixing this 12 liters to A,Qty. of Milk:Water in A=(60+3):9 liters
  So % of water in A=(9/63)*100=100/7 or 14.28
