Answer:
Selling price of watch A and watch B= Rs. 425
Let cost price of watch A=x
Profit =10%
∴
100
110
x=425
x=386.36
Let cost price of watch B=y
Loss =10%
∴
100
90
y=425
y=472.22
Net cost price =x+y=858.5858
Net selling price =850
Loss%=
858.58
858.5858−850
×100=1%

Answer:
D
Explanation:
Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).
The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.
Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.
