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:
2
Explanation:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
Answer:
True
Explanation:
You must first observe your data then form a hypothesis.
Potassium and Chloride forms an ionic bond.
(K+) + (Cl-) = KCl
Potassium is under Group IA (Alkali Metal), wherein elements under this group can easily lose electrons.
Chlorine is under Group VII (Halogens), in which these elements can gain electrons easily.
The inner shell electrons on potassium will merge with the outer shell of electrons of chlorine to make potassium chloride.
