Neha's present age is 3rd of her aunt's present age. Neha's brother is 18 yearsolder to Neha. The respective ratio between the present ages of Neha's brotherand Neha's aunt is 17:24. What is Neha's present age ?1) 24 years2) 14 years3) 26 years4) 18 yearsA rect5) 16 years​

Answer»

Answer:

so neha's present age is 5 years

Step-by-step EXPLANATION:

Let Nisha's age is x years

Aisha's age = (x² + 2) years

Now, A/C to question , when Nisha grows to her mother present age .means Nisha's grows = Aisha's present age - Nisha's present age = x² + 2 - x

Then, this TIME Aisha's age = Aisha's present age + GROWING time = x² + 2 + x² + 2 - x = 2x² - x + 4

Now, question SAID , Aisha's age = 10× times of Nisha's age -1

2x² - x + 4 = 10x -1

2x² - 11x + 5 = 0

2x² -10x - x + 5 = 0

x = 5 and 1/2 x ≠ 1/2 because age doesn't in moths

Hence , Nisha's present age = 5 years

Aisha's present age = (5)² + 2 = 27 years

10. The difference of two numbers is 20. f of the smaller is 14 more than half ofthe greater. Find the numbers.​

Answer»

Let x be the larger number and y be the smaller number

Therefore x-y=20%of x

Now put the value of smaller number in the EQUATION

x-20=(20÷100)×x

x-20=(1/5)×x

Here 5 is in denominator.

As we BRING 5 on the left side of equation it will be multiplied by x-20

Now the equation will be 5 ×(x-20)=x

5x-100=x

Bring 100 on RIGHT side of = and x on the left side of =

So it will become 5x-x=100

4x=100

x=100÷4

x=25

Therefore the larger number is 25

500 रुपयांवरील द.सा.द.शे. 10 टक्के चक्रवाढ व्याज दराने 2 वर्षाची रास व 3 वर्षाची रास यातील फरक किती​

Answer»

Given:

500 रुपयांवरील द.सा.द.शे. 10 टक्के चक्रवाढ व्याज दराने 2 वर्षाची रास व 3 वर्षाची रास यातील फरक किती

To find:

फरक किती

Solution:

The sum of money, P = Rs. 500

The rate of interest, R = 10% p.a.

Compound Interest for 2 years:

The no. of years, N = 2 years

A = P [1 + \frac{R}{100} ]^n

\implies A = 500 [1 + \frac{10}{100} ]^2

\implies A = 500 \times  [\frac{110}{100} ]^2

\implies A = 500 \times  [1.1]^2

\implies A = 605  

and

C.I. = A - P = 605 - 500 = <klux>105</klux>

 

Compound Interest for 3 years:

The no. of years, n = 3 years

A = P [1 + \frac{R}{100} ]^n

\implies A = 500 [1 + \frac{10}{100} ]^3

\implies A = 500 \times  [\frac{110}{100} ]^3

\implies A = 500 \times  [1.1]^3

\implies A = 665.50  

and

C.I. = A - P = 665.50 - 500 = 165.50

Now,  

The required difference is,

= C.I.₃ - C.I.₂  

= Rs. 165.50 - Rs. 105

= Rs. 60.50

 

Thus, the difference between the compound interest for 2 years and 3 years at the rate of 10% on Rs.500 is → Rs. 60.50.

[Q.] If one end of the diameter of the circleis the point (–3, 2), then its other end is the point ?● Correct answer is:- ( 11 , 12) I want only steps....please give solutions. ​

Answer»

Question :-

If one end of the DIAMETER of the circle  x^{2} + y^{2} -8x - 14y + c = 0  is the point (–3, 2), then  its other end is the point ?

Answer:-

⇒ As , General equation of circle is

x^{2} + y^{2} + 2gx + 2fy + K = 0 -----(1)

⇒ one end of circle is is B: ( -3 , 2 ) and other is A: ( a , b )..

⇒ As , given equation of circle is

x^{2} + y^{2} -8x - 14y + c = 0

 comparing with equation (1)..

We  get ,

           g = - <klux>4</klux> and f = - 7

As, we KNOW that CENTER of circle is : C = ( -g , -f )

⇒ So, center is C : ( 4 , 7 ).

So, by using mid point

( 4 , 7 ) =( \frac{a-3}{2}  , \frac{b + 2}{2} )

∴ 8 = a - 3 . ⇒ a = 11

14 = b + 2 . ⇒ b = 12

So,

    another point is A(a,b) = ( 11,12 )

A circle touches all the four sides of a quadrilateral ABCD with AB = 6 cm. BC = 7 cmand CD = 4 cm. Find AD.​

Answer»

ANSWER:

AD=3cm

Step-by-step explanation:

Given : A circle inscribed in a quadrilateral ABCD,AB=6cm,BC=7cm,CD=4cm.

To find : AD

Proof : Let the circle touch the sides AB,BC,CD,DA, at P,Q,R and S, respectively.

AP=AS          

BP=BQ                     

DR=DS                   

CR=CQ  {LENGTHS of two tangents drawn from an external point of circle, are EQUAL}

Adding all these, we get

(AP+BP)+(CR+RD)=(BQ+QC)+(DS+SA)

AB+CD=BC+DA

⇒6+4=7+AD

⇒AD=10−7=3cm.

1. Consider the line passing through the points (1.3) and (4,9).a) What is the slope of the line ?b) What is the equation of the line ?c) Find the coordinates of the point at which the line cuts the x-axis ?​

Answer»

Answer :-

a.) Slope of the line = \dfrac{2}{1} \:\:\text{or}\:\:2

b.) Equation of the line - y = 2x + 1

c.) The coordinates of the POINT at which the line cuts the x-axis is (-0.5, 0)

Solution :-

Let the points be A(1,3) and B(4,9).

Here,

x_1= 1,\:\:\:\:x_2=4\\y_1 = 3,\:\:\:\:y_2=9

a.) Slope of the line = \dfrac{y_2-y_1}{x_2-x_1}

Slope of the line AB = \dfrac{9-3}{4-1} = \dfrac{6}{3}= \dfrac{2}{1} \:\:\text{or}\:\:2

b.) Equation of the line - y - y_1=m(x - x_1)

y = y coordinate of second point  

m = slope  

x = x coordinate of second point

=> y - 3=2(x-1)

=> y - 3 = 2x -2

=> y = 2x - 2 + 3

=> y = 2x + 1

c.) It is given in the question that we have to FIND the coordinates of the point at which the line cuts the x-axis. This INDICATES that y- coordinate of that point is 0 because it cuts x - axis.

=> y = 2x + 1

=> 0 = 2x + 1

=> -1 = 2x

=> \dfrac{-1}{2} =x

=> -0.5 = x

The point is - (-0.5, 0)

Answer»

Answer:

Option (b)

Step-by-step explanation:

Given:-

50% of (x- y) = 40% of (x + y)

To find:-

If 50% of (x- y) = 40% of (x + y), then what percent of x is y?

Solution:-

Given that

50% of (x- y) = 40% of (x + y)

=>50% × (x- y) = 40% ×(x + y)

=>(50/100)× (x- y) = (40/100)× (x + y)

= (1/2)×(x- y) = (2/5)× (x + y)

=>(x -y)/2 = 2(x + y)/5

=>(x-y)/2 = (2x+2y)/5

On applying cross MULTIPLICATION then

=>5(x-y) = 2(2x+2y)

=>5X -5y = 4x +4Y

=>5x -4x = 4y +5y

=>x = 9y -----(1)

Let A% of x = y

=>A% ×x = y

=>(A/100)× x = y

=>A×9y/100 = y

=>A9y/100 = y

On cancelling y both sides

=>9A /100 = 1

=>9A = 1×100

=>9A = 100

=>A = 100/9%

=>A = 11 1/9 %

Answer:-

The required percentage for the given problem is

11 1/9 %

Solve:A) Find the mean of all prime numbers up to 10.(B) Find the mean proportional between 3 and 27. (C) Divide 81 in to three parts in the ratio 2 : 3 : 4 (D) Given below figure shows a pair of parallel lines cut by a transversal. Find thevalue of a and b, giving reason.

Answer»

Answer:

1.) The all prime NUMBERS UPTO 30 are 2,3,5,7,11,13,17,19,23,29

sum of these observations=129

Number of their observation=10

Required mean=129÷10=12.9

2.)The mean proportional of 27 and 3 is √27×3=√81=9.

3.)GIVEN ratio=2:3:4

Sum of their ratio=9

1st part=2/9×81=18

2nd part=3/9×81=27

3rd part= 4/9×81=36

4.)Each figure given below shows a pair of parallel lines cut by a TRANSVERSAL For each case, find a and b, giving reasons.
