Question

In what ratio is water to be mixed with milk at ₹16.50 per litre to make the price of the mixture ₹15 per litre.​

Answer 1

Step-by-step explanation:

You are paying for the milk and not the water, so

there is +15%2F16.5+ as much milk as before

+%28+16.5+-+15+%29+%2F+16.5+=+1.5%2F16.5+ is the fraction

of water to make up the difference

---------------------------------

The ratio of milk to water is +15%2F1.5+=+10%2F1+
