100 liters of milk solution with concentration of 40% is heated so as to evaporate the water. After the heating process is over, concentration of milk solution increases to 50%. What is the final quantity of the milk solution after heating?
after evaporating ratio becomes 1:1 ,since milk will not evaporate
M:W=2:2
earlier 2 x+3x=5x=100 now 2+2= 4x=80lt
i am getting 80 lt
in case if the answer is 60 lt and milk in it is 50% which is 30lt , how can it happen that milk gets evaporated because the initial solution had 40 lt of milk
Since, the Selling Price is not increased, to keep the profit percentage same the cost price of total mixture needs to be brought back to the original level by mixing the impurity
CP ___________New CP 100___________120 to bring back to the original level 120 ___________ 100 , % change = (20/120 ) x 100 = 16.66% = 1/6
