Question

A solution contains 30g of sugar dissolved in 370g of water calculate the contiontretion of the solution.

​

Answer 1

Answer:

Let the number be X

So according to condition

Half of the number is X/2

One third of the number is X/3

One sixth of the number is X/6

Average of all three numbers will be

=> (X/2+ X/3+ X/6)/3 = X/3

And number is 6 more than the average, so

=> X= 6+X/3

=> 2X/3 = 6

=> X= 9

Hence the number is 9

Answer 2

Answer:

mass of sugar = 30 g

=> total mass of solution = 400 g(30gm+ 370 g)

=> percentage of sugar = 30/400 * 100%

= 7.5%

Hope this helps u :)
