[ In a mixture of 45 litres, the ratio of milk to water is 13:2. How much water
must be added to this mixture to make the ratio of milk to water as 3:12
m afhin the number of pirls in school of 50 pupils is​

Answer 1

Answer:

13x+2x=45

15x=45

x=3

Total milk=13*3=39

Total water=2*3=6

Let x be added to this mixture

39+x:6+x=3:12

12(39+x)=3(6+x)

468+12x=18+3x

12x-3x=18-468

9x=-450

x=-50
