A dishonest milkman sells milk at cost price but he mixes water and earns 50/3% profit. Find the ratio of milk and mixture in the mixture. Please explain it logically. Thank u.

say the milk costs C rupees per liter, and the dishonest milkman mixes x liters milk and 1-x liters water to make the one liter milk
He sells the mixed liter of milk at C rupees but the actual cost to him (assuming water doesn’t cost anything is xC rupees only)
Hence he makes a profit of
C-xC rupees = 50/3% of the cost which is xC
thus


hence milk:water = 6:1
