Question 17. A Can Contains A Mixture Of Two Liquids A And B In The Ratio 7: 5. When 9 Litres Of Mixture Are Drawn Off And The Can Is Filled With B, The Ratio Of A And B Becomes 7: nine. How Many Litres Of Liquid A Were Contained By The Can Initially?

Answer :

Suppose the can to start with contains 7x and 5x litres of mixtures A and B respectively

Quantity of An in mixture left 

= (7x - 7/12 x 9) litres = (7x - 21/four) litres.

Quantity of B in aggregate left 

= (5x - five/12 x 9) litres = (5x - 15/4) litres.

(7x - 21/four) / [(5x - 15/4) +9] = 7/9 = › 28x - 21/20x + 21 = 7/nine =› 252x - 189 = 140x + 147

 (3 - 3x/eight + x) = (5 - 5x/8) = 5x + 24 = 40 - 5x 

=› 10x = 16 =› x = eight/five

So, a part of the combination changed = (8/five x 1/8) = 1/5.
