Arthur runs an Electronics shop. He recently bought a new air conditioner for ₹32,000 . He sold the AC for ₹28,000.What is Arthur's loss percent?

Answer»

➥QUESTION

Arthur RUNS an ELECTRONICS shop. He recently bought a NEW air CONDITIONER for ₹32,000 . He sold the AC for ₹28,000.What is Arthur's loss percent?

➥SOLUTION

Bought a new AC = ₹32,000

Sold that AC for = ₹28,000

Cost Price = 32,000

Selling Price = 28,000

Formula to FIND loss percent:

32,000-28,000 = 4,000

LOSS % =

$\huge\frac{loss}{cost \: price} \times 100$

LOSS = 4,000

COST PRICE = 32,000

$\huge \frac{4000}{32000} \times 100 = 12.5\%$

ANSWER 12.5%

13.	(3/7)²m ÷ (3/7) -4 = (3/7)-8
Answer» ANSWER: the value of m is -4 Step-by-step explanation: $\frac{ {3}^{2} }{7} m \div \frac{3}{7} - 4 = \frac{3}{7} - 8$ $\frac{9}{49} m \div \frac{3}{7} - 4 = \frac{3}{7} - 8$ $\frac{9}{49} m \times \frac{7}{3} - 4 = \frac{3}{7} - 8$ NOW , CUT 3 BY 9 AND 7 BY 49 THEN YOU WILL GET, $\frac{3}{7} m - 4 = \frac{3}{7} - 8$ NOW TRANSFER -4 TOWARDS RIGHT HAND SIDE $\frac{3}{7} m = \frac{3}{7} - 8 - 4$ $\frac{3}{7}m = \frac{3}{7} - 4$ HENCE THE VALUE OF M IS -4

13.

(3/7)²m ÷ (3/7) -4 = (3/7)-8

Answer»

ANSWER:

the value of m is -4

Step-by-step explanation:

$\frac{ {3}^{2} }{7} m \div \frac{3}{7} - 4 = \frac{3}{7} - 8$

$\frac{9}{49} m \div \frac{3}{7} - 4 = \frac{3}{7} - 8$

$\frac{9}{49} m \times \frac{7}{3} - 4 = \frac{3}{7} - 8$

NOW , CUT 3 BY 9 AND 7 BY 49

THEN YOU WILL GET,

$\frac{3}{7} m - 4 = \frac{3}{7} - 8$

NOW TRANSFER -4 TOWARDS RIGHT HAND SIDE

$\frac{3}{7} m = \frac{3}{7} - 8 - 4$

$\frac{3}{7}m = \frac{3}{7} - 4$

HENCE THE VALUE OF M IS -4

An open water tank 12m long 9m wide and 4m deep is to be made. Determine the cost of iron sheet required at the rate of Rs. 25 per m, if the sheet is 1.5 m wide.Note- Show in steps

Answer»

ANSWER:

Rs . 6400 is the cost of iron required

Step-by-step explanation:

Length l=12m

Breadth b=9m

Height h=4m

⇒ TOTAL surface of the TANK =2(l×b+b×h+h×l)

=2(12×9+9×4+4×12)

=2×(108+36+48)

=192×2

=384m2

⇒ Length of the SHEET required =384 / 1.5

=256 m

∴ Cost of the sheet =256×25

=Rs .6400

∴ Total cost of the sheet =Rs.6400

Hence, the answer is Rs. 6400

Estimate the cost of painting the inner wall of a well , if the depth of the well is 14ft and the diameter is 8ft . the cost of painting 2.5 sq. ft is 20 rupee? Explain

Answer»

Question:

Estimate the cost of painting the inner wall of a WELL , if the depth of the well is 14ft and the DIAMETER is 8ft . the cost of painting 2.5 sq. FT is 20 rupee? Explain

Given:

Depth (height) of well (cylinder) = 14ft

Diameter of well (cylinder) = 8ft

Cost of painting 2.5 sq.ft = ₹20

Formula used:

$\bold{C.S.A\:of \: cylinder = 2\pi rh}$

Solution:

$\bold{C.S.A\:of \: cylinder = 2\pi rh}$

$\bold{ = \cancel{2}×\dfrac{22}{\cancel{7}}×\dfrac{8}{\cancel{2}}×\cancel{14}}$

$\bold{ = 22×8×2}$

$\bold{ = 352\:sq.ft}$

$\bold{Cost of painting 2.5 sq.ft = ₹20}$

$\bold{Cost of painting 1 sq.ft = \dfrac{₹20}{2.5}}$

$\bold{Cost of painting 352 sq.ft = \dfrac{₹20}{2.5}×352}$

$\bold{Cost of painting 352 sq.ft = \dfrac{₹7040}{2.5}}$

$\bold{Cost of painting 352 sq.ft = ₹2816}$

$\bold{∴\:The \:cost\:of\:painting\:the\:inner\:wall\:of\:the\:well=₹2816}$

3. Determine the nature of roots of the following quadratic equations.x²-4x+4=0

Answer»

Given:

Equation → x² - 4x + 4

To find:

Nature of roots = ?

FORMULA USED:

$\rm{For \: finding\:the\:nature\:of\:roots,}\\\\\bf{D = b^{2} - 4ac}\\\\\tt{where,}\\\\\star \quad \sf{D=Discriminant}\\\star \quad \sf{a = <klux>1</klux>}\\\star \quad \sf{b = -4}\\\star \quad \sf{c=4}$

D = b² - 4ac

⇒ D = (-4)² - 4(1)(4)

⇒ D = 16 - 16

∴ D = 0

Since D = 0, the given quadratic equation has 1 real and equal root.

Additional Information:

If D > 0, the equation will have 2 real and distinct roots.
If D < 0 , the equation will have 2 non real or imaginary roots.
