liquid A in the ratio 1 : 2, the second having water and
liquid B in the ratio 1 : 3, and the third having water
and liquid C in the ratio 1 : 4. These three mixtures of
A, B, and C, respectively, are further mixed in the
proportion 4 : 3 : 2. Then the resulting mixture has

poured into a fourth vessel, then find the
ratio of milk and water in fourth vessel.
10. The ratio of milk and water in four vessels
are 1 : 2, 3 : 2, 7 : 3 and 1 : 1. The ratio of
capacity of all vessels are in the ratio 1 : 2 : 3
: 4. All are poured into a fifth vessel, then
find the ratio of milk and water in fifth
vessel.
12. The ratio of milk and water in a mixture is 3 :
7. We added 10 lt water to the mixture then
ratio becomes 1 : 3. Find the initial quantity of
milk.
(a) 10 lt (b) 15 lt (c) 11 lt (d) 13 lt
13. ***:
A solution of salt and water contains 15% salt by weight. 30 kg of
water evaporates, and the solution now contains 20% of the salt. The
original quantity of the solution is
14. Ratio between milk and water in a
mixture to 4 : 3. When 18 liters of water
is added In the mixture then ratio
becomes 2 : 3. Find initial quantity of
water.
