वर्गकाे क्षेत्रफल.=144cm2 भए यसकाे लम्वाइ कति हाेला ?( If area of square =144cm2 ,What is length of its side?)
area of square =144cm2
Length of square(l) =?
Area of square =(l)2
or,144cm2=(l)2
or,(l)2=(12cm)2
l=12cm
area of square =144cm2
Length of square =?
Area of square =(l)2
or,144cm2=(l)2

What are fact about regular pentagone?
The value of interior angle of regular pentagone=108°.
The value of exterior angle of regular pentagone = 180o−108o = 72o
formula to find interior angle of regular polygone(x) =(nn−2) 180o = (55−2)180o = 108o
formula to find exterior angle of regular polygone(y)= n360o = 5360o=72o
Which of the below answers are correct.
Which of below are correct answers?
Which are correct answers?
If C.P.=Rs 300
S.P=Rs Rs 330
Find profit or loss
Solution:Profit =S.P-C.P
=RS 330-RS300=Rs 30
If S.P.=Rs 300
C.P=Rs Rs 330
Find profit or loss
Solution:Loss =C.P-S.P
=RS 330-RS300=Rs 30
If C.P.=Rs 300
S.P=Rs Rs 330
Find profit or loss
Solution:Profit =S.P+C.P
=RS 330+RS300=Rs 630
ख) उत्तर, C.P.=Rs 5000
S.P=Rs 4500
C.P>S.P So, loss=?
Loss=CP-S.P
=Rs5000-Rs4500
=Rs500
ख) उत्तर, C.P.=Rs 5000
S.P=Rs 4500
C.P>S.P So, profit=?
Profit=CP-S.P
=Rs5000-Rs4500
=Rs500

costing price (C.P),selling price(S.P.) profit (P), loss(L)
Which are correct?
Real Profit=
selling price -costing price
(P=S.P-C.P)
......................................
Real loss= costing price-selling price
(L= C.P-S.P)
Selling Price= Real profit+ Costing Price
(S.P=P+C.P)
.......................................
Costing Price=Selling Price- real profit
(C.P=S.P-P)
Profit %
=C.P.Real profitX100 % .......................................................
Loss % =C..Preal lossX 100 %
costing price= Real loss +Selling price
(C.P=L +S.P)
......................................
selling price=costing price-real loss
(S.P=C.P-L)
Selling Price= Real profit-Costing Price
(S.P=P-C.P)
.......................................
Costing Price=Selling Price+ real profit
(C.P=S.P+P)

find diameter and circumference of given circleclick on best option.
Solution:
r= 14 cm
D=?
∵D=2r
=2 X 14 cm =28 cm
Solution:r= 14 cm, C=?
∵C=2πr
=2X 722X 14 =88cm
∵c= πD
= 722X 28 cm
=22X4cm=88 cm

बन्दीको नियम( Closure proerty)
If a and b are any two integer then
a+b is also integer
For eg. (+2) and (+5) are integer then
(+2) + (+5) =(+7)is also integer .
Commutative property
( क्रम विनिमय नियम)
If a and b are any two integer then
a+b =b+a
For eg. (+2) and (+5) are integer then
(+2) + (+5) =(+5)+(+2)
Associatve property
(सङ्घीय नियम)
If a,b and c are any three integer then
[a+b]+c =a+[b+c]
For eg. (+2) +(+5) +(+3) are three integer then
(+2) + (+5) +(+4)=[(+5)+(+2)]+(+4)
=(+7)+(+4)
=(+11)
again,(+2) + (+5) +(+4)=(+5)+[(+2)+(+4)]
=(+5)+(+6)
=(+11)

Q.1)
if A={ Natural number less than 5},B={Odd number less than 9},C={Prime factors of 18 } ,D={Cube number between 5 and 10 }
i) Which of the following sets are equivalent sets ?.)
ii) Is the sets D being subset of Set C write with reasons .
iii)Write Universal set - of sets A and B.
Hints
A={ Natural number less than 5}={1,2,3,4}
,B={Even number less than 9}={2,4,6,8}
,C={ factors of 18 } ={1,2,3,6,9,18}
,D={Square number between 5 and 10 }={ 9 }
click which are correct answers?
i) Solution : Set A and B are equivalent sets .
Ii) Solution: yes , set D being subset of Set C because member 9 is Present in both sets C and D .
iii)Solution: A={ Natural number less than 5}={1,2,3,4}
B={Even number less than 9}={2,4,6,8}
universal set of sets A and B : U = {1,2,3,4,5,6,7,8}
iii)Solution: A={ Natural number less than 5}={1,2,3,4}
B={Even number less than 9}={2,4,6,8}
universal set of sets A and B : U = {1,3,5,7,9}
i) Solution : Set C andD are equivalent sets .
