  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
