20l of mixture cintains milk and water in the ratio 5:3. If 4l of mixture is replaced by 4l of milk, the ratio of milk to water in the new mixtute would be

Answer 1

volume of mixture=20L

if 4L mixture is removed then,

volume of mixture=16L

volume of water=3÷(5+3)×16

=6L

volume of milk=5÷8×16

=10L

if 4Lmilk is added then,

volume of milk=10+4

=14L

ratio of milk and water=14:6

=7:3
