0.17 A shopkeeper allows a discount of 10% on an article and still makes a profitof 25%. What will be the cost price for an article whose marked price is 900.

Answer»

let the COST price of the article US 100

then if shopkeeper allows 10 % discount

price will be 90 .

and 25 % PROFIT MEANS

$\frac{ 90\times25 }{100} = 22.5$

then the price will be 90 + 22.5

= 112.5

if 112.5 on 100 then

$\frac{112.5}{100} = \frac{900}{x}$

112.5 × x = 90000

x =

$\frac{90000}{112.5} = <klux>800</klux>$

22.	If x⁴+1/x⁴ =119, find x²+1/x² and x +1/xPlease answer the question with explanation
Answer» EXPLANATION. ⇒ If x⁴ + 1/x⁴ = 119. As we know that, ⇒ (x² + 1/x²)² = x⁴ + 1/x⁴ + 2(x²)(1/x²). ⇒ (x² + 1/x²)² = x⁴ + 1/x⁴ + 2. Put the value of (x⁴ + 1/x⁴) = 119 in EQUATION, we get. ⇒ (x² + 1/x²)² = 119 + 2. ⇒ (x² + 1/x²)² = 121. ⇒ (x² + 1/x²) = √121. ⇒ (x² + 1/x²) = 11. As we know that, ⇒ (X + 1/x)² = x² + 1/x² + 2(x)(1/x). ⇒ (x + 1/x)² = x² + 1/x² + 2. Put the value of (x² + 1/x²) = 11 in equation, we get. ⇒ (x + 1/x)² = 11 + 2. ⇒ (x + 1/x)² = 13. ⇒ (x + 1/x) = √13. Value of (1) = x² + 1/x² = 11 and (2) = x + 1/x = √13.

22.

If x⁴+1/x⁴ =119, find x²+1/x² and x +1/xPlease answer the question with explanation

Answer»

EXPLANATION.

⇒ If x⁴ + 1/x⁴ = 119.

As we know that,

⇒ (x² + 1/x²)² = x⁴ + 1/x⁴ + 2(x²)(1/x²).

⇒ (x² + 1/x²)² = x⁴ + 1/x⁴ + 2.

Put the value of (x⁴ + 1/x⁴) = 119 in EQUATION, we get.

⇒ (x² + 1/x²)² = 119 + 2.

⇒ (x² + 1/x²)² = 121.

⇒ (x² + 1/x²) = √121.

⇒ (x² + 1/x²) = 11.

As we know that,

⇒ (X + 1/x)² = x² + 1/x² + 2(x)(1/x).

⇒ (x + 1/x)² = x² + 1/x² + 2.

Put the value of (x² + 1/x²) = 11 in equation, we get.

⇒ (x + 1/x)² = 11 + 2.

⇒ (x + 1/x)² = 13.

⇒ (x + 1/x) = √13.

Value of (1) = x² + 1/x² = 11 and (2) = x + 1/x = √13.

Answer»

Answer:

MP is always expressed as a percentage of CP.

Discount is always applied on MP.

Profit is always expressed as a percentage of CP.

Coming to the problem :

MP = 250

Discount = 10% of MP = 25

SP = MP - Discount

Since he is making 25% profit on goods sold, then SP REPRESENTS 125% of CP.

G) 11 ice cubes, each having a side of 2 cm, are melted. If the water is poured in acylindrical glass of the radius 20 cm, how much of the glass will be filled? Find theheight. (Use pie = 22/7)

Answer»

Answer:

0.07 cm

Step-by-step explanation:

Volume of 1 ice cube = a^3 = 2^3

= 8 cm^3

Volume of 11 ice CUBES = 8*11 = 88cm^3

Volume of cylindrical glass = Volume of 11 ice cubes

pie*r^2h = 88

22/7*20*20*h = 88

h = 88*7/20*20*22

h = 0.07 cm
