12.	How much many will be required to buy 250 rs 15 shares at a discount of 1.50
Answer» Given: Rs 15 shares at a discount of 1.50 To FIND: How much MANY will be required to BUY 250. Solution: Now we have number of shares which are to be bought: 250 Now Rs 15 shares at a discount of Rs 1.5 which MEANS the nominal value of the share is Rs 15 and its market value will be: 15 - 1.5 = 13.5 Rs Now money required to buy 1 share = Rs 13.5 So money required to buy 250 shares: Rs 13.5 x 250 = Rs 3375 Answer: Rs 3375 will be required to buy 250 shares.

12.

How much many will be required to buy 250 rs 15 shares at a discount of 1.50

Answer»

Given: Rs 15 shares at a discount of 1.50

To FIND: How much MANY will be required to BUY 250.

Solution:

Now we have number of shares which are to be bought: 250

Now Rs 15 shares at a discount of Rs 1.5 which MEANS the nominal value of the share is Rs 15 and its market value will be:

15 - 1.5 = 13.5 Rs

Now money required to buy 1 share = Rs 13.5

So money required to buy 250 shares:

Rs 13.5 x 250 = Rs 3375

Answer:

Rs 3375 will be required to buy 250 shares.

If the number of term in (1+x)^n be 11, find the 5th term and the value of n

Answer»

SOLUTION

GIVEN

$\sf{The \: number \: of \: terms \: in \: \: {(1 + x)}^{n} \: is \: 11}$

TO DETERMINE

The VALUE of n

5 th term

EVALUATION

Here it is given that

$\sf{The \: number \: of \: terms \: in \: \: {(1 + x)}^{n} \: is \: 11}$

We know that

$\sf{The \: number \: of \: terms \: in \: \: {(1 + x)}^{n} \: is \: (n + 1)}$

So by the given condition

n + 1 = 11

∴ n = 10

Hence the required value of n = 10

5 th term

$= \sf{t_5}$

$= \sf{t_{4 + 1}}$

$= \sf{ {}^{10}C_4 \: {x}^{4} }$

$= \sf{ 210 \: {x}^{4} }$

Find the remainder (without division) when 8x2+5x + 1 is divisible by x – 10

Answer»

Given : 8x² +5x + 1 is DIVIDED by x - 10

To Find : Remainder

Solution:

Using remainder theorem :

if polynomial p(x) is divided by x - m

then remainder is p(m)

and if p(m) = 0 then (x - m) is a factor

p(x) = 8x² +5x + 1

divided by x - 10

Hence m = 10

so remainder =p(10)

p(10) =8(10)² +5(10) + 1 = 851

Verification by division

8x + 85

x - 10 _| 8x² +5x + 1 |_

8x² - 80x

_______

85x + 1

85x - 850

__________

851

VERIFIED that remainder is 851

47.	If x=a, y=b is the solution of the equations x-y=21 and x+y=41, then the values of a and b are
Answer» Answer: x = a = 31 and y = b = 10 Step-by-step EXPLANATION: Here, x - y = 21 x = 21 + y ... ( 1 ) Substituting the value of x from ( 1 ) in other EXPRESSION: ⇒ x + y = 41 ⇒ ( 21 + y ) + y = 41 ⇒ 21 + y + y = 41 ⇒ 21 + 2Y = 41 ⇒ 2y = 41 - 21 ⇒ 2y = 20 ⇒ y = 20 / 2 ⇒ y = 10 Hence, x = 21 + y = 21 + 10 = 31 Hence x = 31 and y = 10

47.

If x=a, y=b is the solution of the equations x-y=21 and x+y=41, then the values of a and b are

Answer»

Answer:

x = a = 31 and y = b = 10

Step-by-step EXPLANATION:

Here,

x - y = 21

x = 21 + y ... ( 1 )

Substituting the value of x from ( 1 ) in other EXPRESSION:

⇒ x + y = 41

⇒ ( 21 + y ) + y = 41

⇒ 21 + y + y = 41

⇒ 21 + 2Y = 41

⇒ 2y = 41 - 21

⇒ 2y = 20

⇒ y = 20 / 2

⇒ y = 10

Hence,

x = 21 + y

= 21 + 10

= 31

Hence x = 31 and y = 10
