Vessel A : 30g sugar mixed in 180ml water.
So, the concentration of sugar in vessel
A is
g∕ml i.e.,
g∕ml Vessel B : 40g sugar mixed in 280ml water.
So, the concentration of sugar in vessel
B is
g∕ml i.e.,
g∕ml Vessel C : 20g sugar mixed in
100ml water.
So, the concentration of sugar in vessel
C is
g∕ml i.e.
g∕ml More the concentration of sugar, more will be the sweetness.
Therefore, in terms of sweetness :
C>A>B
