|
Answer» Answer: 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
= 25 16×1000
=640 ml Hence the AMOUNT of water required =360 ml. Ratio =640:360 =16:9 |
