Question

4 litre of a 10% kerosine mixed 20 litre petrol, 3 litre petrol evaporates the percentage of kerosine is
​

Answer 1

Answer:

Suppose the initial ratio of Petrol  and Kerosine is 3x and 2x

Quantity of Petrol in mixture left =(3x−  

5

3

​  

×10)=(3x−6)

Quantity of Kerosine in Mixture left =(2x−  

5

2

​  

×10)(2x−4)

⇒  

2x−4+10

3x−6

​  

=  

3

2

​  

 

⇒9x−18=4x+12

⇒x=6

Than total quality of mixture =3x+2x=18+12=30
