Today we shall learn about the 6 questions that are coming in objective category.
These are basically fundamental question which are taken from mainly all the chapters . For this we have to go through the concepts of each of the chapter and the theorem of geometry and their application.
What you have to revise in this are as follows.
1. Formula for algebra
2. Application of concepts in Arithmetic , Geometry, Mensuration etc.
--------------------------------------------------------------------------------------
We will list below the formula that will be useful here. List will be continued.
---------------------------------------------------------------------------------------
1. Profit = S.P - C.P
2. Loss = C.P - S.P
3. Profit % = Profit
------- X 100
C.P
4. Loss % = Loss
------- X 100
C.P
5. S.I = PxRxT
--------- , P = Principal , R = Rate , T = Time
100
6. Amount=P(1+r/100)^n , where A=Amount , P=Principal, r=Rate , n =time , in compound interest.
7. If a^2 + b^2 =0, then a=0 and b=0.
8. In geometry , We know that the sum of opposite angles of a cyclic quadrilateral is 180.
9. The sum of the adjacent angles are 180.
10. The external angle of a triangle is equal to the sum of the interior opposite angles.
11. If x<=a, then the maximum value of a will be a.
12. To remember all trigonometric values of sine , cos, tan, cot, sec ,cosec of 0,30,45,60,90.
13. The angle subtended at the centre will be double that of the angle at the circumference in a circle.
14. The area of the triangle betweens the parallels is equal to the half of the area of the parallelogram.

In Physical science we have to go through the following : - ( 1st Unit Test )
Differentiate between :- (Remember 2 points only)
a. Atomic Model and Solar System.
b. Atomic Number and Mass Number
c. Real and Virtual Images

g. Atom and Ion.
h. Convex Lens and Concave Lens
i. Electrovalent and Ionic Compound.
Define
a. Atom ,Atomic Number , Mass number, Ion, Cation , Anion. Isotope Atomic Mass on C-16 scale.
d. Boyles Law, Charles Law, Avogadro's Hypothesis, Avogadro's Number.
e. Heat, Temperature, Specific Heat, Water Equivalent , Principle of Calorimetry.
f. Oxidation , Reduction, Oxidant , Reductant.
g. Chemical Bonding, Electrovalent bonding, Covalent Bonding, Ionic or Electrovalent compound, Covalent compound.
h. Lens, Convex Lens , Concave Lens, Focus, Focal Point, Focal Length, Optical Centre, Radius of Curvature , Centre of Curvature, Linear Magnification, Refraction, Dispersion , Spectrum , Pure and Impure Spectrum.

For calculation what we have to remember is (1st unit test only . List will continue..........)
a. C F-32
---- = ------ (where C= Celsius or Centigrade and F= Fahrenheit.
5 9
b. Q = mst , where m = mass of the body, s= specific heat, t= temerature.
c. Q = mL , where m= Mass, L= Latent Heat.
d. 1 mole= 6.023 x 10^23 = 22.4 litre = molecular weight in grams.
