A fruit seller bought some fruits for 6000 and sold them at a profit of 9%. Find his selling price in details

Answer»

wer :-

Given :-

COST price = RS. 6000
Profit PERCENTAGE = 9%

To Find :-

SELLING price

Solution :-

We know that,

$\sf \bigstar \: \sf{S.P = \dfrac{100+Gain\%}{100} \times C.P}$

Substituting the value in formula :-

$\implies\sf SP = \dfrac{100 + 9}{100} \times 6000$

$\implies\sf SP = 109 \times 60$

$\implies\sf SP = 6540$

Selling price = Rs. 6540

$\begin{gathered}\begin{gathered}\begin{gathered} \small\boxed{ \begin{array}{cc}\large\sf\dag \: {\underline{More \: Formula}} \\ \\ \bigstar \: \sf{Gain = S.P – C.P} \\ \\ \bigstar \:\sf{Loss = C.P – S.P} \\ \\ \bigstar \: \sf{Gain \: \% = \Bigg( \dfrac{Gain}{C.P} \times 100 \Bigg)\%} \\ \\ \bigstar \: \sf{loss \: \% = \Bigg( \dfrac{loss}{C.P} \times 100 \Bigg)\%} \\ \\ \bigstar \: \sf{ C.P =\dfrac{100}{100+Gain\%} \times S.P} \\ \\\bigstar \: \sf{ S.P = \dfrac{100-loss\%}{100} \times C.P} \\ \\ \bigstar \: \sf{ C.P =\dfrac{100}{100-loss\%} \times S.P}\end{array} }\end{gathered}\end{gathered} \end{gathered}$

Answer» ong>Step-by-step explanation: (a) LET the consecutive numbers be (x) and (x+1) x + x + 1 = 15 2x = 15 - 1 2x = 14 x = 14/2 x = 7 x + 1 = 7 + 1 = 8 So the numbers are 7 and 8 (b) Let the NUMBER be x 2x - 5 = 60 2x = 60 + 5 2x = 65 x = 65/2 x = 32.5 So the number is 32.5 (c) I tried to solve but I can't really sorry. (d) let the number be x 6x = 54 x = 54/6 x = 9 So the number is 9 (e) Let the number be x x / 6 = 5 x = 5 × 6 x = 30 So the answer is 30 Hope it helps!!

Please help me find out the answer I am request you to find out the answer

Answer»

ong>Step-by-step explanation:

(a) LET the consecutive numbers be (x) and (x+1)

x + x + 1 = 15

2x = 15 - 1

2x = 14

x = 14/2

x = 7

x + 1 = 7 + 1 = 8

So the numbers are 7 and 8

(b) Let the NUMBER be x

2x - 5 = 60

2x = 60 + 5

2x = 65

x = 65/2

x = 32.5

So the number is 32.5

(c) I tried to solve but I can't really sorry.

(d) let the number be x

6x = 54

x = 54/6

x = 9

So the number is 9

(e) Let the number be x

x / 6 = 5

x = 5 × 6

x = 30

So the answer is 30

Hope it helps!!

${\small{\underline{\boxed{\sf{Volume \: of \: cylinder \: = \pi r^{2} h}}}}}$

${\large{\pmb{\sf{\underline{\maltese \: \: Full \; Solution...}}}}}$

~ As we already know that the when paper rolled to cylinder then length be circumference and breadth be the height of the cylinder. HENCEFORTH, by using given formula let us find the radius.

${\small{\underline{\boxed{\sf{Circumference \: of \: circle \: = 2 \pi r}}}}}$

$\sf :\implies Circumference \: of \: circle \: = 2 \pi r \\ \\ \sf :\implies 88 \: = 2 \times 3.14 \times r \\ \\ \sf :\implies 88 \: = 6.28 \times r \\ \\ \sf :\implies \dfrac{88}{6.28} = \: r \\ \\ \sf :\implies 14 \: = r \\ \\ \sf :\implies r \: = 14 \: cm \\ \\ \sf :\implies Radius \: is \: 14 \: cm$

~ Now by using the given formula let us find the volume of the cylinder that is formed.

${\small{\underline{\boxed{\sf{Volume \: of \: cylinder \: = \pi r^{2} h}}}}}$

$\sf :\implies Volume \: of \: cylinder \: = \pi r^{2} h \\ \\ \sf :\implies Volume \: of \: cylinder \: = 3.14 \times 14^{2} \times 40 \\ \\ \sf :\implies Volume \: of \: cylinder \: = 3.14 \times 14 \times 14 \times 40 \\ \\ \sf :\implies Volume \: of \: cylinder \: = 3.14 \times 196 \times 40 \\ \\ \sf :\implies Volume \: of \: cylinder \: = 615.44 \times 40 \\ \\ \sf :\implies Volume \: of \: cylinder \: = 24617.6 \: cm^{3}$

Bloom, Bubbly, and Buttercup share a triple sundae. They pay Rs 30 for it. But the ice-cream realizes that he charged more than he should. He sends his associate to return them five rupees. Since it is hard to split 5 rupees, among three friends, the associate keeps two rupees for himself and returns one rupee each to the customers. This means, Bloom, Bubbly and Buttercup each paid nine rupees for the icecream and two rupees as tips for the associate. This totals 29 rupees. How much money is left

Answer»

ey left with three FRIENDS is RS 3 ( Rs 1 with each )

Money with associates is Rs 2

Solution:

Total Paid = Rs 30

Owner Returned Rs 5

NET Paid = 30 - 5 = Rs 25

Each Person GET rs 1 back

Hence paid = Rs 9 each

Total Paid by 3 = 3 * 9 = 27 Rs

Actually net paid = Rs 25

27 - 25 = Rs 2 is the difference what associate had

there is no meaning of adding 27 & 2 = 29 and COMPARE with 30

its actually

27 - 2 = 30 - 5

=> 25 = 25

Money left with three friends is Rs 3 ( Rs 1 with each )

Money left with associates is Rs 2

Answer» wer :-<P> Let the length be 3x and breadth be 2x. We know that, Area = Length × Breadth Substituting the values :- → 216 = 3x × 2x → 216 = 6x² → x² = 216 / 6 → x² = 36 → x = 6 Length = 6 × 3 = 18 m Breadth = 6 × 2 = 12 m → PERIMETER = 2 ( Length + Breadth ) → P = 2 ( 18 + 12 ) → P = 2 ( 30 ) → P = 60 Perimeter of RECTANGLE = 60 m

49.

The length and breadth of a rectangle are in the ratio 3:2. If the area of the rectangle is 216sq.m, then find the length of the rectangle and also find the perimeter.

Answer»

wer :-<P>

Let the length be 3x and breadth be 2x.

We know that,

Area = Length × Breadth

Substituting the values :-

→ 216 = 3x × 2x

→ 216 = 6x²

→ x² = 216 / 6

→ x² = 36

→ x = 6

Length = 6 × 3 = 18 m
Breadth = 6 × 2 = 12 m

→ PERIMETER = 2 ( Length + Breadth )

→ P = 2 ( 18 + 12 )

→ P = 2 ( 30 )

→ P = 60

Perimeter of RECTANGLE = 60 m
