A milk vendor sells milk at Cost Price but still gains 20%. Find the ratio of milk and water in every gallon that he sells.
A. 4:1
B. 5:1
C. 5:2
D. 6:1
E. None of these

• B. 5:1
  Let Rs 100 be cost price and selling price
  To get 20% profit by selling at Rs 100, quantity to be actual sold =100*100/120=250/3,
  In case of milk to compensate for the quantity water to be mixed=100-250/3=50/3
  Therefore the ratio of milk:water=250/3:50/3=5:1
