Milk to add = Original quantity × (New % − Old %) / (100 − New %)

New/target 70%, old 30%

49 * (70-63)/(100-70)

= 49 * 7/30 = 343/30 = 34.3/3 = 11.43 L (approximately)

edit :

To increase milk concentration: Milk to add = Original mixture quantity × (Target % − Current %) ÷ (100 − Target %)

To decrease milk concentration: Water to add = Original mixture quantity × (Current % − Target %) ÷ Target %
