Question

Hey can anyone plz help me understand this question
The percentage of salt in 1 l of water is 10%. If 500ml of water is added to this mixture what percentage of salt is there now.

I am doing
10/100 times 1500

Answer 1

The added water is 1.5l not 1500
10/100 =1l
X/100=1.5l
X=15 percent

Answer 2

No the answer is 6 times 2/3

Answer 3

1l = 1000 ml
ok
if 500ml is added then
1000+500=1500 liters are there
in 1000 liter % of salt is 10%
then in 500 literes %of salt is half of 10 that is 5%
so in 1500liters there is 15 % of salt

Answer 4

Does the added water have salt in it

Answer 5

Hey @Orion1213 do u have any idea? Thnx for helping again

Answer 6

initially with respect to volume of water:
1000 + 500 = 1500
considering % of salt solution:
0.1(1000) + 0 = 1500x
x = 0.1(1000)/1500 = 0.0666666666667
in %:
100x = 6.67% = 6 and 2/3 percent....

Answer 7

@Orion1213 how did u get 0.1(1000)

Answer 8

10% of 1 li.(1000ml) of salt = 0.1(1000)
