Answer:
b) 120 Its
Step-by-step explanation:
Let, Quantity of original solution = 100x
Then quantity of salt = 15x
When 30kg of water is evaporated then total quantity= 100x -30
But quantity of salt will remain same and now quantity of salt is 20% of original quantity
(100x -30)*1/5 = 15x
X = 120 kg
