Krushit  (3 years ago)

Mixture of salt & water = 60 litre

Salt % = 70%

70% Salt = (70/100) * 60 = 42 Litre

Water = 60 - 42 = 18 Litre

Let say x litre water is added

then Misxture = 60 + x litre

Salt = 42 Litre

Salt % = 60%

(42/(60+x) ) * 100 = 60

=> 70 = 60 + x

=> x = 10

10 litre of water need to be added
