If 500 gm of salt solution has 30% salt in it, how
much salt must be added to make the concentration
of salt 50% in the solution?​

Answer 1

Answer:

The mass of the salt is 500×30%=150 gm

Say the mass of salt added is x gm

Then from the given condition

(150+x)/(500+x)=50/

Simplifying the above equation we get

x=200 gm

The amount of salt added is 200 .
