Question

chemical A and chemical B are mixed in the ratio x:y to make chemical C . the cost of A is 120 per liter , cost of B is 300 per liter , cost of C is 273 per liter . Then find x:y​

Answer 1

Step-by-step explanation:

Let us assume that he sells just one liter of the solution

cost of chemical = Rs. 25.

selling price = Rs. 20.

profit = 25 %

CP=SP(

100+P%

100

)

=20(

100+25

100

)=

125

20×100

=

5

80

=16

For Rs. 25, he can buy 1 liter.

So, For Rs. 16, he can buy

25

1×16

l

=

25

16×1000

=640 ml

Hence the amount of water required =360 ml.

Ratio =640:360

=16:9
