Answer 1

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
