Maths Puzzle
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 : 9. How many litres of liquid A was contained by the can initially?
Read Solution (Total 1)
-
- 21 litres
If initial quantities of A and B are 7x and 5x respectively, then
(7x-21/4) /(5x+21/4) = 7/9
solving it, we get,
x=3
hence initial quantity of A in initial mixture =7*3= 21 ltrs. - 12 years agoHelpfull: Yes(5) No(21)
