Question

Milk and water is mined in the ratio 4:3 to make 42 litter. How much more milk is to be added to make the ratio 2:1

Answer 1

Answer:

16.8

Step-by-step explanation:

4x+3x =42

》5x=42

》x=42/5

》x=8.4

to make the ratio 2:1 we have to make milk 6x(dubble of 3x)

the milk was 4x=4×8.4=33.6

and the milk will be 6x=6×8.4=50.4

so we have to add 50.4-33.6=16.8littee

Answer 2

4:3 makes 42 litre of mixture

4x+3x=42

7x=42

x=6

then 4(6)= milk =24 litre

3(6)=water= 18

so if we want to make the ratio of 2:1 then milk have to become double than water.

so water is 18 then milk have to 36

36-24=12

12 litre milk required to make the ratio of 2:1
