16 liter ... i used the mixture method .... Given that, A : B ( 4 : 1) , (2 : 3) ----- Liquid B is added so A is constant Then, ( 4:1) x 1 , ( 2: 3) x 2 = 4 : 1 , 4 : 6 ------>(6 - 1) 5 parts is 10 ... 1 part is 2, (4 + 1)5 part is 10 ... 10 + 10( liquid B added ) = 20 (mixture ) .... Asked Liquid A , i.e., 16 Liter ( 5 part is 20, 1 part is 4, So, 20 - 4 = 16 liter )

Hi RItu ... phela tho its the 2nd homework question ka solution..... 1st homework answer is : 6 litres .... Given that initial mixture 3 : 2 after adding liquid B it is 1 : 4 .... since Liquid A is Constant So, (3 : 2) x 1 , (1 : 4) x 3 ....( 3 : 2 ) ( 3 : 12) ..... (12 - 2) 10 units is 6 litre ...... 1 units is 3/5 .... So, initial liquid mixture is 10 lit ------> 3 ( 5 x (3/5) ) + 7 ( Mixture taken out) = 10 lit ... Initial Quantity of A in vessel is 10 x ( 3/5) = 6 lits ... Hope you understood ...... if any doubt feel free to ask... GOD BLESS...

they asked u about the Liq A initially...i.e Before adding Liq B..Answer would be 8L Two Ratios-4:1 and 4:6..5 Parts =10...1part=2... Therefore Liq A present initially =4 parts=8L answer
