Question

20 litres of a mixture contains milk and water in the ratio 5:3. If 4 litres of
mis mixture be replaced by 4 litres of milk, find the ratio of milk to water in
the new mixture.​

Answer 1

Answer:

sum of the terms of the ratio is 5+3=8

total litres of mixture =20litres

no.of.litres of milk is 5÷8×20=25/2

no.of.litres of water is 3/8 × 20=15/2

4litres of milk is added

25/2 + 4=33/2

the new ratio is 33/2 : 15/2

=33/2 × 2/15

=11/5

=11:5
