10.	1. The price of a VCR inclusive of GST is Rs. 13,530. If the rate of GST is 10%, find its basic price
Answer» ONG>Given, The PRICE of the VCR is Rs. 13530 which is inclusive of GST. GST rate is 10%. To find, The basic price of the VCR. Solution, Let, the basic price of the VCR = Rs. x (ASSUME, x as a variable to do the further mathematical calculations.) GST amount on the basic price = ( x × 10/100) = Rs. x/10 Final price (inclusive GST) = (x + x/10) = Rs. 11x/10 Now, if we compare the VALUES of the final PRICES, we will get the following mathematical equation, 11x/10 = 13530 x = 13530 × 10/11 x = 12300 Hence, the basic price of the VCR is Rs. 12300

1. The price of a VCR inclusive of GST is Rs. 13,530. If the rate of GST is 10%, find its basic price

Answer» ONG>Given,

The PRICE of the VCR is Rs. 13530 which is inclusive of GST.

GST rate is 10%.

To find,

The basic price of the VCR.

Solution,

Let, the basic price of the VCR = Rs. x

(ASSUME, x as a variable to do the further mathematical calculations.)

GST amount on the basic price = ( x × 10/100) = Rs. x/10

Final price (inclusive GST) = (x + x/10) = Rs. 11x/10

Now, if we compare the VALUES of the final PRICES, we will get the following mathematical equation,

11x/10 = 13530

x = 13530 × 10/11

x = 12300

Hence, the basic price of the VCR is Rs. 12300

16.	A rectangleis 20cm long and 10cm wide .A square with the same perimeter as this rectangle will have an area of
Answer» >Area of a square = 225 cm² Given :– Length of a RECTANGLE = 20 CM long. Breadth of a rectangle = 10 cm wide. A square with the same perimeter as this rectangle. To Find :– Area of a square. Solution :– We know that, Perimeter of a rectangle = 2(length + breadth) / 2(l + b) We have, Length = l = 20cm. Breadth = b = 10cm. $\longmapsto2(20 cm+ 10cm)$ $\longmapsto2(30 \: cm)$ $\longmapsto60 \: cm$ According to the CONDITION, Perimeter of a rectangle = Perimeter of a square Perimeter of a rectangle = 60cm. That means, Perimeter of a square = 60cm. So, We know that, Perimeter of a square = 4 × side $\longmapsto 60 \: cm = 4 \times side$ $\longmapsto \cancel\dfrac{60}{4} \: cm = side$ $\longmapsto15 \: cm = side$ Side of a square is 15 cm. Now, we have to find the area of a square. Area of a square = (side)² side = 15 cm. $\longmapsto { (15 \: cm) }^{2}$ $\longmapsto15 \: cm\times15 \: cm$ $\longmapsto225 \: {cm}^{2}$ Hence, The area of a square is 225 cm².

16.

A rectangleis 20cm long and 10cm wide .A square with the same perimeter as this rectangle will have an area of

Answer»

>Area of a square = 225 cm²

Given :–

Length of a RECTANGLE = 20 CM long.
Breadth of a rectangle = 10 cm wide.
A square with the same perimeter as this rectangle.

To Find :–

Area of a square.

Solution :–

We know that,

Perimeter of a rectangle = 2(length + breadth) / 2(l + b)

We have,

Length = l = 20cm.
Breadth = b = 10cm.

$\longmapsto2(20 cm+ 10cm)$

$\longmapsto2(30 \: cm)$

$\longmapsto60 \: cm$

According to the CONDITION,

Perimeter of a rectangle = Perimeter of a square

Perimeter of a rectangle = 60cm.

That means,

Perimeter of a square = 60cm.

So,

We know that,

Perimeter of a square = 4 × side

$\longmapsto 60 \: cm = 4 \times side$

$\longmapsto \cancel\dfrac{60}{4} \: cm = side$

$\longmapsto15 \: cm = side$

Side of a square is 15 cm.

Now, we have to find the area of a square.

Area of a square = (side)²

side = 15 cm.

$\longmapsto { (15 \: cm) }^{2}$

$\longmapsto15 \: cm\times15 \: cm$

$\longmapsto225 \: {cm}^{2}$

Hence,

The area of a square is 225 cm².

28.

Two complementary angles differ by 12 degrees then the angles are

Answer»

ong>ANSWER:

we know the sum of two complementary angles are 90°, so,

let the number be 'x'

another angel = x-12

so, x+ x- 12 = 90°

= 2x -12 = 90°

= x = 102/2

hence, x = 51..

then, the first angle = 51°

and another angle = x -12 = 51 -12 = 39°
