Question

A person has a chemical of Rs.50 per litre. In
what ratio should water be mixed in that
chemical, so that after selling the mixture at
Rs.40 per litre he may get a profit of 50%?​

Answer 1

Step-by-step explanation:

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

cost of chemical = Rs. 50

selling price = Rs. 40

profit = 50%

CP = SP (100/100+P%)

= 40 (100/100+ 50)

=( 40×100)/150 = 4000/150 = 26.67

For Rs. 50, he can buy 1 liter.

So, For Rs. 26.67, he can buy (1×26.67 )/50 litre

= (1000×26.67)/50= 533.4 ml

Hence the amount of water required = 1000 - 533.4

= 466.6 ml

Ratio = 533.4/466.6 = 2667/2333
