15 years ago, Narendra Father's age was four times of Narendra's age. Now Narendrafather's age is 6 years more than twice of Narendra's age. Find their ages?​

Answer»

Solution

Given :-

  • 15 years ago, NARENDRA Father's age was four times of Narendra's age

  • Now Narendrafather's age is 6 years more than twice of Narendra's age.

Find :-

  • Present age of Narendra & Narendra Father 's

Explanation

According to question

Case 1.

==> present age of Narendra Father's = (X + 6)

==> present age of Narendra = x

Case 2.

==> (x + 6 - 15) = 4(x - 15)

==> x - 9 = 4x - 60

==>4x - x = -9 + 60

==> 3x = 51

==> x = 51/3

==> x = 17

Hence

  • Present age of Narendra Father's = (x + 6) = 17 + 6 = 23 years
  • Present age of Narendra = 17

If the radius of sphere is doubled find the %change in volume​

Answer»

Step-by-step explanation:

LET the RADIUS be R

Now the surface area = 4π(r) ² = 4πr²

The radius of the sphere is doubled.

The radius = 2r.

Now the surface area = 4π(2r)² = 16πr² .

Increase % in area = 16πr²-4πr²/4πr² * 100 = 12/4*100 = 300% .

The ratio of amount of money with Ram and Rekha is 5 : 3, if Rekha has 750 rupees what is Ram’s share ?

Answer»

ANSWER:

Let the RATIO be 5X and 3x

let the Ram’s share be y

5x/3x = y/750

5/3 = y/750

y = (5 × 750) ÷ 3

y = 3750 ÷ 3

y = 1250

therefore, Ram's share is 1250 RUPEES.

Volume of a conical water tank is 864 cubic meter. If the diameter of the base is 14 m, what will its height be?

Answer»

Given :-  

  • Volume of a conical water tank is 864 cubic meter.  
  • If the diameter of the base is 14 m

To Find :-  

  • what will its height be?

SOLUTION :-  

~Here, we’re given the volume of a conical tank and it’s diameter. From the given diameter we can find the radius and then the height of the conical tank by applying the FORMULA of volume of a cone.  

______________

As we know that ,  

\sf \bigstar \;\; Radius = \dfrac{Diameter}{2}  

\sf \bigstar \;\; Volume\;of\;cone = \dfrac{1}{3} \times ( \pi r^{2} h )  

Where,  

  • h is height  
  • r is radius  

______________

Finding the Radius :-  

\sf \implies \dfrac{14}{2}

\sf \leadsto 7\; m 

Finding the height :-  

\sf \implies 864\;m^{3} = \dfrac{1}{3} \times \dfrac{22}{7} \times 7 \times 7 \times h 

\sf \implies 864 = \dfrac{154}{3} \times h

 

\sf \implies h = 864 \times \dfrac{3}{154}

 \sf \leadsto h = 16.83 \; m

______________

HENCE,

  • Height of the conical tank is 16.83 m

Find the distance between the points A(3,-3) & B (7,-5)​

Answer»

Step-by-step explanation:

distance = \sqrt{(x2 - x1)^{2} + {(<klux>Y2</klux> - y1)}^{2} }

Here (x1, y1)=(3,-3) and (x2, y2)=(7,-5)

USING the formula,

distance = \sqrt{ {(7 - 3)}^{2} + {( - 5 - ( - 3))}^{2} }

distance = \sqrt{4^{2} + ( - 2)^{2} }

distance = \sqrt{16 + 4} = \sqrt{20}

5 A cubical box has each edge 10 cm and another cuboidal box is 12.5 cm long, 10 cmwide and 8 cm high.(1) Which box has the greater lateral surface area and by how much?Which box has the smaller total surface area and by how much?ncluding​

Answer»

Step-by-step explanation:

(i) LATERAL surface area of cubical box = 4a2 = 4 x 102 = 400 cm2

Lateral surface area of cuboidal box = 2h (l + b)

= 2 x 8(12.5 +10) = 16 X 22.5 = 360 cm2

Thus, lateral surface area of cubical box is greater by

(400 cm2 - 360 cm2) = 40 cm2

(ii) Total surface area of cubical box = 6A2 = 6 x 102 cm2 = 600 cm2

Total surface area of cuboidal box = 2 (lb + bh + hl)

= 2(12.5 x 10 + 10 x 8 + 8 x 12.5)

= 2(125 + 80 + 100) = 2 x 305cm2 = 610 cm2

Thus, total surface area of cuboidal box is greater by (610 - 600) cm2

= 10 cm2

6. The present ages of A and B are 23 years and 31years respectively. After how many years the ratiobetween their ages will be 11 : 13?is​

Answer»

{\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}

Given:

  • Present age of A = 23years
  • Present age of B = 31 years

\\

To FIND:

  • The NUMBER of years after which the ratio between their ages will be 11:13

\\

Assumption:

  • Let the number of years be x.

\\

Solution:

So,

⇒ Age of A after x years = (23 + x) years

⇒ Age of B after x years = (31 + x) years

Hence,

\implies (23 + x) : (31 + x) = 11 : 13 \\\implies \dfrac{23 + x}{31 + x} = \dfrac{11}{13}

On Cross- Multiplying,

⇒ (13)*(23 + x) = (11)*(31 + x)

⇒ 299 + 13x = 341 + 11x

⇒ 13x - 11x = 341 - 299

⇒ 2x = 42

⇒ x = 21

So, after 21 years the ratio between the ages of A and B will be 11:13.

\\

Verification:

⇒ Age of A after x years = (23 + x) years = 23 + 21 = 44 years

⇒ Age of B after x years = (31 + x) years = 31 + 21 = 52 years

⇒ Ratio of ages of A and B = 44:52

On dividing by 4,

⇒ Ratio of ages of A and B = 11 : 13

Hence verified too!
