Let pencil be x and let pen be y5x+7y=507x+5y=46multiply first equation by 735x+49y = 350multiply second equation by 535x+25y=230solving them we get 24y=120 which gives y is 5 rupeessubstituting in second equation we get x is 3 rupees

Let the cost of a table is Rs t and cost of a chair is Rs c.

Given

2t + 3c = Rs 2000 ----------------1

And

3t + 2c = Rs 2500 -----------------2

Solve these two linear equations

Multiply eqn 1 by 3 and eqn 2 by 2

6t + 9c = 6000 -----------3

6t + 4c = 5000------------4

Subtract Eqn 4 from 3

5c = 1000

c = 200

Substitute the value of c in eqn 1

2t + 3*200 = 2000

2t + 600 = 2000

2t = 1400

t = 700

The cost of a table is Rs 700 and Cost of 5 chairs = 5 * 200= Rs 1000.

Let cost of one pencil be xLet cost of one pen be y

Then,5x + 7y = 50x = (50 - 7y)/5.......(1)

7x + 5y = 46......(2)

Put value of x from eq(1) in eq(2), we get 7*(50-7y)/5 + 5y = 46350 - 49y + 25y = 230-24y = - 120y = 120/24 = 5

x = (50 - 7*5)/5 = 15/5 = 3

Therefore, cost of pencil is Rs 3 and cost of pen is Rs 5

let cost(in RS) of one pencil = x and cost (in RS) of one pen = yTherefore , according to question 5x+7y = 50 ........ (1) 7x + 5y = 46 .........(2) Multiply equation 1 by 7 and equation by 5 we get 7(5x+7y)= 7*50 35x +49y = 350 .......(3) and 5(7x +5y) = 5*46 35x +25y = 230 ....... (4)

Subtract equation 4 from equation 3 , we get 35x + 49y - 35x - 25y = 350 -230 49y -25y = 120 24y = 120 y = 120 /24 y= 5Substitute y=5 in equation 1 , we get 5x + 7*5 =50 5x+35 =50 5x = 50 - 35 5x =15 x= 15/5 x=3

Hence Cost of One Pencil = x =3 Cost of One Pen =y =5

Since we are working with metres, we convert the speed into m/s

We do this by multiplying the speed in km/h by 5/18

45×5/18=25/2

This gives :12.5m/s

The distance covered excluding the first post we have :5×30=150m

For us to get the time taken we use the formulae : Time=Distance/Speed

150m/12.5m/s=12

The time taken is 12 seconds.

Solution:(3) 41

Explanation:

5² + 12² = 169 => 13²

8² + 15² = 289 => 17²

7² + 24² = 625 => 25²

9² + 40² = 1681 => 41²

let the volume of water in the second tank be x

and the volume of water in the first tank = 2x

ATQ

2x - 25 = x + 25

2x - x = 50

x = 50

now ,

volume of water in ist tank = 2x = 2(50) = 100 litres

thank you

72400 is the correct answer of the given question

Given : Rate of pencil is ₹16 per score Rate of pens is 8.40 per dozen

To Find : Ratio of the prices

Solution :

Score is used for 20 items

1 Score = 20 pencils

Dozen is used for 12 items

1 Dozen = 20 ball pens

Now ,

Rate of one pencil = x

20 pencil = ₹ 16

x = 16/20

x = 8/10

x = Rs.0.8

Rate of one ball pen

12 ball pens = ₹ 8.40

x = 8.4/12

x = 84/120

x = 7/10

x = Rs.0.7

Ratio of pencil and ball pen = 0.8/0.7 = 8:7

As you can see that AB || CD so , Angle abc and bcd are alternate interior angles so they are equal. so angle BCD = 75 Now angle BCD + X = 180° SO X = 180-75 = 105°

First find prime factors of 336 and 54

336 = 2, 2, 2, 2, 3, 754 = 2, 3, 3, 3

HCF ( 336 , 54 ) = 2 × 3 = 6

LCF( 336 , 54 ) = 2^4 × 3^3 × 7 = 3024

We know that ,

For any two positive integers a and b .

HCF( a , b ) × LCM( a , b ) = a × b

Verification :

HCF( 336 , 54 ) × LCM( 336 , 54 )

= 6 × 3024

= 18144 -----( 1 )

a × b = 336 × 54 = 18144 ----( 2 )

Therefore ,

( 1 ) = ( 2 )Hence proved

89 9/12 = 1077 / 12= 89.75= 90

A cubic polynomial has 3 zeros as it has 3 degree

Let the CP of each pen be Rs.x.

Then,

CP of 12 pens=Rs.12

SP of 12 pens=CP of 15 pnes=Rs.15

now,gain=SP-CP=Rs.(15-12)=Rs.3

gain%=gain/cp*100

=(3/12*100)%=25%

Hence,the gain=25%.
