Question

In a mixture of 45liters 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 to 3:1 (please re9 ASAP)​

Answer 1

Dear Student,

⇒Answer :  

Let x litres of water is added,

Original mixture has water = $\frac{ 2 }{ 15 }$ × 45

New mixture is 45+x litres & water in it =  $\frac{ 1 }{ 4 }$ (45+x)

Also water is (  $\frac{ 2}{ 15 }$  × 45 )   + x

⇒ $\frac{ 45 + X }{4 }$  = 6 x ⇒  45+x= 24+4 x

⇒ 3 x = 21⇒ x= 71

⇒71 litre water must be added to this mixture to make the ratio of milk to water to 3:1
