Answer:

Bro firstly correct question is-

How many Kg of pure salt must be added to 30 kg of 2% solution of salt and water to increase it to a 10%

Step-by-step explanation:

See the Answer below-

Given : 2% salt must be added to 30 kg solution

Then amount of salt in 30 kg solution =2/100×30=0.6 kg

Let x kg of pure salt added 

∴0.6+X/30+X=10/100

⇒60+100x=300+10x

⇒100x−10x=300−60

⇒90x=240

⇒x=240/90=8/3

Then 8/3kg salt added in solution
