23.	The price of 3 pencil and 4 pen is 24rs for 6 pencil and 3 pen is 27 Rs what is the price of each
Answer» Answer: Let price of one pencil and one pen be be 'a' and 'b' respectively. Step-by-step explanation: Solution: 3a+4b=24 ...........(i) 6a+3b=27 ...........(ii) Solving this by ELIMINATION METHOD , Multiplying 2 in equation (i), 2(3a+4b)=24 =6a+8b=48 ........(iii) 6a+3b=27 .........(ii) Subtract equation (ii) from(iii) 6a+8b=48 _ 6a+3b=27 The sign in 'a' changes and 'a' is cancelled,the sign in b changes,sign of +27 changes to -27. +8b - 3b=+5b 48 - 27=21 5b=21 b=+4.2 Putting value of b in equation(i), we GET value of 'a' as ,a=+2.4 Therefore value of one pencil is 2.4rs and value of one pen is 4.2rs.

23.

The price of 3 pencil and 4 pen is 24rs for 6 pencil and 3 pen is 27 Rs what is the price of each

Answer»

Answer:

Let price of one pencil and one pen be be 'a' and 'b' respectively.

Step-by-step explanation:

Solution:

3a+4b=24 ...........(i)

6a+3b=27 ...........(ii)

Solving this by ELIMINATION METHOD ,

Multiplying 2 in equation (i),

2(3a+4b)=24 =6a+8b=48 ........(iii)

6a+3b=27 .........(ii)

Subtract equation (ii) from(iii)

6a+8b=48

_

6a+3b=27

The sign in 'a' changes and 'a' is cancelled,the sign in b changes,sign of +27 changes to -27.

+8b - 3b=+5b

48 - 27=21

5b=21

b=+4.2

Putting value of b in equation(i),

we GET value of 'a' as ,a=+2.4

Therefore value of one pencil is 2.4rs and value of one pen is 4.2rs.

Please answer correct it is my request

Answer»

Solution !

Q 1:- Coordinate of TWO points. A(3,4) and B(-2,5)

We have to find (Abscissa of A)-(Abscissa of B)

We know that the VALUE of x is abscissa

and value of y = ordinate

Abscissa of A = 3

Abscissa of B= (-2)

(Abscissa of A )-( Abscissa of B)

=> 3-(-2)

= 3+2= 5

Q1 :- Option 3 is the correct ANSWER

Now Q2:-

•x= 3 •y= 1

Q:- 2x+5y= k ,Find the value of k

put the value of x and y in the GIVEN equation

2x+5y= k

2(3) +5(1)= k

6+5=k

11=k

k= 11

40.	at what rate will a borrowed of sum of money charged if it earns 1/4 of itself as interest of 1 year and 9 months
Answer» Given: Interest is 1/4th of the sum of money Time period = 1 YEAR and 9 moths = $1\frac{9}{12} = 1\frac{3}{4} = \frac{7}{4} \: years$ To find: The rate of interest Solution: Let "R" be the rate of interest and "P" be the sum of money Interest received is 1/4th of the sum of money i.e., S.I. = $\frac{P}{4}$ The formula of the simple interest is given by, $S.I. = \frac{PRT}{100}$ Now, we will SUBSTITUTE the given VALUES in the above formula to find the value of R. ∴ $\frac{P}{4} = \frac{P\times R \times \frac{7}{4} }{100}$ cancelling P from both sides ⇒ $\frac{1}{4} = \frac{1\times R \times \frac{7}{4} }{100}$ ⇒ $\frac{100}{4} = 1\times R \times \frac{7}{4}$ ⇒ $100 = 1\times R \times 7$ ⇒ $R = \frac{100}{7}$ ⇒ $\bold{R = 14.28\%}$ Thus, the rate of interest is 14.28%. ------------------------------------------------------------------------------------------------ ALSO VIEW: The interest on a sum of money at the end of 6 1/4 years is 5/16 of the sum itself .

at what rate will a borrowed of sum of money charged if it earns 1/4 of itself as interest of 1 year and 9 months

Answer»

Given:

Interest is 1/4th of the sum of money

Time period = 1 YEAR and 9 moths = $1\frac{9}{12} = 1\frac{3}{4} = \frac{7}{4} \: years$

To find:

The rate of interest

Solution:

Let "R" be the rate of interest and "P" be the sum of money

Interest received is 1/4th of the sum of money i.e., S.I. = $\frac{P}{4}$

The formula of the simple interest is given by,

$S.I. = \frac{PRT}{100}$

Now, we will SUBSTITUTE the given VALUES in the above formula to find the value of R.

∴ $\frac{P}{4} = \frac{P\times R \times \frac{7}{4} }{100}$

cancelling P from both sides

⇒ $\frac{1}{4} = \frac{1\times R \times \frac{7}{4} }{100}$

⇒ $\frac{100}{4} = 1\times R \times \frac{7}{4}$

⇒ $100 = 1\times R \times 7$

⇒ $R = \frac{100}{7}$

⇒ $\bold{R = 14.28\%}$

Thus, the rate of interest is 14.28%.

√3 sinthEta/ 3sinthetha = costheta

1/√3 = costheta

cos square THETA= 1/3

sin squaretheta +cos squaretheta =1

sin squaretheta = 1-1/3 = 2/3

48.

Find the 20 terms of ap whose second term is 14 and third

Answer»

Answer:

common DIFFERENCE (d) = 18-14 = 4

the second TERM = a+d = 14

so, a = 14-4 = 10

SUM

number of TERMS (n) = 51

a = 10

d = 4

Sum=n/2 [2a + (n-1)d]

= 51/2 [20 + (50 x 4)]

= 51/2 [20+200]

= 51 x 110

= 5610

therefore, the sum of 51 terms of AP is 5610
