Use ratios,
15 g : 0.1 L
75 g : x L
solve for x by cross multiplication.
how many litres of 15%(mass/volume)sugar solution would it take to get 75g of sugar?

Let the value be x
15% of (75+x)=75
15/100 of 75+x=75
15(75+x)/100=75
3(75+x)/20=75
3(75+x)=75×20
75+x=75×20/3
75+x=25×20
75+x=500
x=500-75
therefore,
x= 425
15% of (75+x)=75
15/100 of 75+x=75

75+x=500
x=500-75
therefore,
x= 425

Galat solve kiya h

It's wrong answer
Answer 11.3 kuch as raha hai or aapka 425 . Sorry but not clear
Let volume be x
Mass by volume %=m/v ×100
15%=75/x ×100
X=75/15 ×100
X=5×100
X=500 ml
X= 0.5 l ( litres )
Hence proved
