One day each member of Ram’s family consumed some milk and some water. Though
the quantities of milk and water varied for the family members, the total
consumption of the two liquids was exactly 7 litres for each family member. If
Ram had one-fourth of the total milk consumed and one-sixth of the total water
consumed, then what was the ratio of the quantity of milk to that of water
consumed by Ram on that day?

1) 3 : 2
2) 1 : 1
3) 2 : 3
4) Cannot be determined
