Answer»

ong>Question :- Find the RECIPROCAL of 11/5 .

ANSWER :-

As we know that, The reciprocal of a number is EQUAL to 1 DIVIDED by the number.

So,

→ reciprocal of 11/5 = 1 ÷ (11/5)

→ reciprocal of 11/5 = 1 * (5/11)

→ reciprocal of 11/5 = (5/11) (Ans.)

Or,

we can say that, when we MULTIPLY a number by its reciprocal we get 1..

So,

→ (11/5) * reciprocal = 1

→ reciprocal = 1/(11/5)

→ reciprocal = 1 * (5/11)

→ reciprocal = (5/11) (Ans.)

17.

If the mean of the numbers 15, 20, a, 32, bis 25, find b in terms of a

Answer» ONG>Answer:

Step-by-step explanation:

ARITHMETIC MEAN OR MEAN OR AVERAGE :

The arithmetic mean of a set of observations is OBTAINED by DIVIDING the SUM of the values of all observations by the total NUMBER of observations .

Mean = Sum of all the observations / Total number of observations .

MEAN = Σfixi / Σfi

[‘Σ’ Sigma means ‘summation’ ]

FREQUENCY DISTRIBUTION TABLE IS IN THE ATTACHMENT

From the table : Σfixi = 445 + 10p , Σfi = 27 + p

MEAN = Σfixi / Σfi

Given : Mean = 15

15 = (445 + 10p) / (27 + p)

15 × (27 + p) = 445 + 10p

405 + 15p = 445 + 10p

15p - 10p = 445 - 405

5p = 40

p = 40/5 = 8

p = 8

Hence, the value of ‘p’ is 8.

A merchant purchased a Wrist watch for Rs.450 and fixed its list price in such a way that after allowing a discount of 10%,he earns a profit of 20%,Find the list price of the wrist watch?

Answer»

ong>Step-by-step explanation:

$\bf\underline{\underline{\red{Given:-}}}$

A merchant purchased a Wrist WATCH for Rs.450.

After ALLOWING a discount of 10%,he earns a profit of 20%.

$\bf\underline{\underline{\blue{To\:Find:-}}}$

The LIST price of the wrist watch.

$\bf\underline{\underline{\green{Solution:-}}}$

$\rm Let\: the\: list \: price \: of\: the \: watch \: be\: Rs. x$

$\rm Discount \% = 10\%$

$\rm Discount = \dfrac{10}{100}\times list\: price$

$\rm = \dfrac{10}{100}\times x$

$\rm= \dfrac{x}{10}$

$\rm \dashrightarrow Discount = \dfrac{x}{10}$

$\rm Selling\: price = List\: price - Discount$

$\rm = x - \dfrac{x}{10}$

$\rm = \dfrac{ 10x - x}{10}$

$\rm = \dfrac{ 9x}{10}$

$\rm \dashrightarrow \underline{\: \: \underline{\: Selling\: price= \dfrac{9x}{10}\: }\: \:}$

$\rm Now,\: Given\: Cost \: Price \: (CP) = Rs.450$

$\rm Profit\%= 20\%$

$\rm \leadsto Selling \: price = \dfrac{ 100 + Profit\%}{100}\times CP$

$\rm \implies \dfrac{9x}{10}= \dfrac{ 100 + 20}{100}\times 450$

$\rm\implies \dfrac{9x}{10} = \dfrac{ 120}{100}\times 450$

$\rm\implies \dfrac{9x}{10}= 12 \times 45$

$\rm\implies \dfrac{9x}{10}= 540$

$\rm\implies x= 540\times \dfrac{10}{9}$

$\rm\implies x = 600$

$\rm List\: price = x = Rs. 600$

$\underline{\boxed{\purple{\rm \therefore List\: price\: of \: the\: watch = Rs.600}}}$

Plot the following points and write the name of figure thus obtained. Find its perimeter. A (2, 0), B (4, 0), C (2,-2), D (4,-2)

Answer»

ong>Figure we obtained is Rhombus and Area is 16 unit².

Step-by-step explanation:

GIVEN:

Coordinates of the points,

A( -4 , 4 ) , B( - 6 , 0 ) , C( -4 , -4 ) and D( -2 , 0 )

We need to plot the points in the coordinate plane and name the figure. Find the Area of the Figure.

Graph is attached after plotting.

ABCD is a Rhombus as opposite SIDES are parallel and all sides are EQUAL and Diagonals are PERPENDICULAR bisector of each other.

Area of the Rhombus ABCD = Area of the ΔABD + Area of the ΔACD

From the figure,

In ΔABD

Base = 4 unit

HEIGHT = 4 unit

In ΔACD

Base = 4 unit

Height = 4 unit

Area of the Rhombus ABCD = 1/2 × Base × Height + 1/2 × Base × Height

= 1/2 × 4 × 4 + 1/2 × 4 × 4

= 8 + 8

= 16 unit²

Therefore, Figure we obtained is Rhombus and Area is 16 unit².

Answer» N 2, 6, p, 54, q are in continued proportion means 2/6 = 6/p = p/54 = 54/q this gives 2/6 = 6/p p = 66/2 p = 18 p/54 = 54/q 18/54 = 54/q 1/3 = 54/q q = 543 q = 162

9. If 2, 6, p, 54 and q are in continued proportion, find the values of p and q.

Answer» N

2, 6, p, 54, q are in continued proportion

means

2/6 = 6/p = p/54 = 54/q

this gives

2/6 = 6/p

p = 6*6/2

p = 18

p/54 = 54/q

18/54 = 54/q

1/3 = 54/q

q = 54*3

q = 162

In triangles PQR, right angled atQ, PQ = 3cm and PR = 6cm.Determine angle QPR.

Answer»

ong>Answer:

in triangle PQR,

PR is HYPOTENUSE and PQ is ADJACENT

cos THETA= adjacent/hypotenuse =PQ/PR

cos theta =3/6=1/2

cos theta=1/2
