1.	A sum of money was divided between rajeev and ashish so that rageev gets7/19 of the whole amount.if he gets rs.5600,how much was the total sum.
Answer» 15200 GiVen:- Rajeev gets 7/19 of the TOTAL amount. To FIND:- Total amount = ? ANSWER:- Let the total amount ( money ) be x. So, $\implies \sf \: \dfrac{7x}{19} = 5600 (Given) \\ \\ \implies \sf \:7x = 5600 \times 19 \\ \\ \implies \sf \:7x = 106400 \\ \\ \implies \sf \:x = \dfrac{106400}{7} \\ \\ \implies { \underline{ \boxed{\sf{ \purple{\:x = 15200}}}}}$ $\therefore$ The total amount is Rs 15200.

1.

A sum of money was divided between rajeev and ashish so that rageev gets7/19 of the whole amount.if he gets rs.5600,how much was the total sum.

Answer»

15200

GiVen:-

Rajeev gets 7/19 of the TOTAL amount.

To FIND:-

Total amount = ?

ANSWER:-

Let the total amount ( money ) be x.

So,

$\implies \sf \: \dfrac{7x}{19} = 5600 (Given) \\ \\ \implies \sf \:7x = 5600 \times 19 \\ \\ \implies \sf \:7x = 106400 \\ \\ \implies \sf \:x = \dfrac{106400}{7} \\ \\ \implies { \underline{ \boxed{\sf{ \purple{\:x = 15200}}}}}$

$\therefore$ The total amount is Rs 15200.

4.	In the figure, ABCD and BPQ are lines. BP=BC and DQ is parallel to CP. Prove that:a) CP=CD b)DP bisects
Answer» GiVen:- BP = BC $\implies$ ∠BPC = ∠PCB AnSwer:- As the exterior angle is equal to the sum of two opposite INTERIOR ANGLES. $\implies$ ∠BPC + ∠PCB = 4x $\implies$ ∠BPC + ∠BPC = 4x $\implies$ 2∠BPC = 4x $\implies$ ∠BPC = 2x = ∠PCB Now, As DQ \|\| CP ∠QDC = ∠PCB (corresponding angles) $\implies$ ∠QDC = 2x Here the exterior angle is equal to the sum of two opposite interior angles. So, $\implies$ ∠PCB = ∠CPD + ∠PDC $\implies$ 2x = x + ∠PDC $\implies$ ∠PDC = x As ∠QDC = 2x and ∠PDC = x $\implies$ DP bisects ∠CDQ Since ∠PDC = x and ∠CPD and SIDES opposite to equal angles are equal, So, CP = CD Hence proved.

4.

In the figure, ABCD and BPQ are lines. BP=BC and DQ is parallel to CP. Prove that:a) CP=CD b)DP bisects

Answer»

GiVen:-

BP = BC

$\implies$ ∠BPC = ∠PCB

AnSwer:-

As the exterior angle is equal to the sum of two opposite INTERIOR ANGLES.

$\implies$ ∠BPC + ∠PCB = 4x

$\implies$ ∠BPC + ∠BPC = 4x

$\implies$ 2∠BPC = 4x

$\implies$ ∠BPC = 2x = ∠PCB

Now,

As DQ || CP

∠QDC = ∠PCB (corresponding angles)

$\implies$ ∠QDC = 2x

Here the exterior angle is equal to the sum of two opposite interior angles.

So,

$\implies$ ∠PCB = ∠CPD + ∠PDC

$\implies$ 2x = x + ∠PDC

$\implies$ ∠PDC = x

As ∠QDC = 2x and ∠PDC = x

$\implies$ DP bisects ∠CDQ

Since ∠PDC = x and ∠CPD and SIDES opposite to equal angles are equal,

So, CP = CD

Hence proved.

Answer» GIVEN: Total surface area of cone is 17776 m² The radius of cone is 56 m TO FIND: What is the slant height (l) of the cone ? SOLUTION: We have given that, the total surface area of cone is 17776 meter² and the radius of cone is 56 m. We know that the formula for FINDING the total surface area of the cone is:- $\large{\boxed{\bf{\star \: AREA = \pi r (l+r) \: \star}}}$ According to question:- On putting the given values in the formula, we get Take π = 22/7 $\rm{\hookrightarrow 17776 = \dfrac{22}{\cancel{7}} \times \cancel{56} (l + 56)}$ $\rm{\hookrightarrow 17776 = 22 \times (8l + 448) }$ $\rm{\hookrightarrow \cancel\dfrac{17776}{22} = 8l + 448 }$ $\rm{\hookrightarrow 808 = 8l + 448 }$ $\rm{\hookrightarrow 808-448 = 8l }$ $\rm{\hookrightarrow 360 = 8l }$ $\rm{\hookrightarrow \cancel\dfrac{360}{8} = l }$ $\bf{\hookrightarrow <klux>45</klux> = l}$ Slant height = l = 45 m ❝ HENCE, the slant height (l) of the cone is 45 m ❞ ______________________

7.

What is the slant height of cone if the total surface area of cone is 17776 meter cube and the radius of cone is 56 m.?

Answer»

GIVEN:

Total surface area of cone is 17776 m²
The radius of cone is 56 m

TO FIND:

What is the slant height (l) of the cone ?

SOLUTION:

We have given that, the total surface area of cone is 17776 meter² and the radius of cone is 56 m.

We know that the formula for FINDING the total surface area of the cone is:-

$\large{\boxed{\bf{\star \: AREA = \pi r (l+r) \: \star}}}$

According to question:-

On putting the given values in the formula, we get

Take π = 22/7

$\rm{\hookrightarrow 17776 = \dfrac{22}{\cancel{7}} \times \cancel{56} (l + 56)}$

$\rm{\hookrightarrow 17776 = 22 \times (8l + 448) }$

$\rm{\hookrightarrow \cancel\dfrac{17776}{22} = 8l + 448 }$

$\rm{\hookrightarrow 808 = 8l + 448 }$

$\rm{\hookrightarrow 808-448 = 8l }$

$\rm{\hookrightarrow 360 = 8l }$

$\rm{\hookrightarrow \cancel\dfrac{360}{8} = l }$

$\bf{\hookrightarrow <klux>45</klux> = l}$

Slant height = l = 45 m

❝ HENCE, the slant height (l) of the cone is 45 m ❞

An auditorium is 80 m long 32 m wide and 12 m high . Find the maximum length of a rod which will measure its demonsions exactly.

$Length (l) = 80 \:m ,$

$\red{ Maximum \: length \:of \: a \:rod}$

$= \sqrt{l^{2} + w^{2} + h^{2}}$

$= \sqrt{ 80^{2} + 32^{2} + 12^{2} }$

$= \sqrt{ 6400 + 1024 + 144 }$

Answer» Answer: 30 Step-by-step explanation: LET the COST price 'A' be x then the the market price 'B' will be (1+(50/100))x or x+(50/100)x =(150/100)x if he still makes a profit of 20% then selling price'C' will be 20% more then the cost price i.e. x+(20/100)x =(120/100)x. So, discount will be market price 'B' - selling price 'C' = (150/100)x - (120/100)x =(30/100)x i.e. 30% NOTE:- u can 100 as cost price for simpler understanding.

A book with the cost price 'A' is sold at a market price 'B' which is 50% higher than the cost price 'A'. If shopkeeper sells the book at a price 'C' with a discount on 'B', he still gets a profit of 20%.What is the discount percentage a) 20 b)30 c)10 d)40

Answer»

Answer:

30

Step-by-step explanation:

LET the COST price 'A' be x

then the the market price 'B' will be

(1+(50/100))x or x+(50/100)x =(150/100)x

if he still makes a profit of 20%

then selling price'C' will be 20% more then the cost price i.e.

x+(20/100)x =(120/100)x.

So, discount will be market price 'B' - selling price 'C'

= (150/100)x - (120/100)x

=(30/100)x

i.e. 30%

NOTE:- u can 100 as cost price for simpler understanding.

35.	Two points A (-2, 9) and B (4, 8) lie on a line l. Find the distance between points A and B.
Answer» Given: Two points: A(-2, 9) B (4, 8) These points lie on a straight line. To FIND: Distance between the two points = ? i.e. AB = ? Solution: We can use Distance formula to find the distance between two points on a line. Distance formula is given as: $D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ D is the distance between the two points whose coordinates are $(x_1, y_1)$ and $(x_2, y_2)$ . Here, the points are A and B which have the following values: $x_1 = -2\\x_2 = 4\\y_1 = 9\\y_2 = 8$ Now, USING the formula: $AB = \sqrt{(4-(-2))^2+(8-9)^2}\\\Rightarrow AB = \sqrt{(6)^2+(-1)^2}\\\Rightarrow AB = \sqrt{36+1}\\\Rightarrow AB = \sqrt{37}\ units$ So, the distance between the points A and B is $\sqrt{37}\ units$ .

35.

Two points A (-2, 9) and B (4, 8) lie on a line l. Find the distance between points A and B.

Answer»

Given:

Two points:

A(-2, 9)

B (4, 8)

These points lie on a straight line.

To FIND:

Distance between the two points = ?

i.e. AB = ?

Solution:

We can use Distance formula to find the distance between two points on a line.

Distance formula is given as:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

D is the distance between the two points whose coordinates are $(x_1, y_1)$ and $(x_2, y_2)$ .

Here, the points are A and B which have the following values:

$x_1 = -2\\x_2 = 4\\y_1 = 9\\y_2 = 8$

Now, USING the formula:

$AB = \sqrt{(4-(-2))^2+(8-9)^2}\\\Rightarrow AB = \sqrt{(6)^2+(-1)^2}\\\Rightarrow AB = \sqrt{36+1}\\\Rightarrow AB = \sqrt{37}\ units$

So, the distance between the points A and B is $\sqrt{37}\ units$ .
