4.	A flooring tile has the shape of parallelogram whose base is 24 cm and height is 20 cm. How many such tiles are required to cover a floor of area 4800 cm ^ 2
Answer» ong>ANSWER : 10 tiles Explanation : A parallelogram-shaped tile with BASE 24cm & height 20cm. Find the number of tiles required to floor 4800cm² Here, Number of required tiles : → AREA of the floor ÷ Area of the tiles The tile is in shape of parallelogram. We know that, Area of a parallelogram : base × height Where, base = 24cm. height = 20cm. ∴ Area of the tile - 24 × 20 = 480cm² ∴ Required tiles : 4800 ÷ 480 = 10

4.

A flooring tile has the shape of parallelogram whose base is 24 cm and height is 20 cm. How many such tiles are required to cover a floor of area 4800 cm ^ 2

Answer»

ong>ANSWER :

10 tiles

Explanation :

A parallelogram-shaped tile with BASE 24cm & height 20cm.

Find the number of tiles required to floor 4800cm²

Here,

Number of required tiles :

→ AREA of the floor ÷ Area of the tiles

The tile is in shape of parallelogram.

We know that,

Area of a parallelogram : base × height

Where,

base = 24cm.
height = 20cm.

∴ Area of the tile - 24 × 20 = 480cm²

∴ Required tiles : 4800 ÷ 480

= 10

Three times a number a 'm' subtracted from 8 is equal to —1?.what is the value of m GIVE THE ANSWER STEP WISE

Answer»

Correct QUESTION:

✰ Three times a number 'm' subtracted from 8 is equal to -12.

To find:

✠ The value of m.

Solution:

LETS understand the concept first! Here, we are given that the three times a number 'm' which means 3 multiplied by the number 'm' i.e, 3 × m = 3m and the number is subtracted from 8 which means we will MINUS the number from 8 i.e, 8 - 3m is equal to - 1. Thus forming a requisite equation and doing the REQUIRED calculations, we will find out the value of m that is the required number.

Let's find out...✧

According to question,

➛ 8 - 3m = - 12

➛ - 3m = - 12 - 8

➛ - 3m = - 20

➛ m = -20/-3

➛ m = 20/3

∴ The value of m = 20/3

Verification:

L.H.S

➛ 8 - ( 3 × 20/3 )

➛ 8 - ( 1 × 20 )

➛ 8 - 20

➛ - 12

= R.H.S

Numbers :- 4x and 3x
Product of these two numbers is 432.

${\underline{\underline{\sf{ \dag \: To \: find :}}}}$

Difference of two numbers.

${\underline{\underline{\sf{ \dag \: Solution :}}}}$

● Let, first find VALUE of x.

${\sf{ \ratio \longmapsto{4x \times 3x = 432}}} \\ \\ {\sf{ \ratio \longmapsto{12 {x}^{2} = 432}}} \\ \\ {\sf{ \ratio \longmapsto{ {x}^{2} = \dfrac{432}{12} }}} \\ \\ {\sf{ \ratio \longmapsto{ {x}^{2} = 36}}} \\ \\ {\sf{ \ratio \longmapsto{x = \sqrt{36} }}}\\ \\ { \underline{ \boxed{ \green{\sf{ \ratio \longmapsto{x = 6}}}}}}$

● Now two of these numbers are

${\sf{ (1) \longmapsto{4x = 4(6) = {\boxed{\green{\sf{24}}}}}}} \\ \\ {\sf{ (2) \longmapsto{3x = 3(6) = {\boxed{\green{\sf{18}}}}}}}$

_______________________________________

● Now, Difference between two numbers is :-

$\large{\red{\sf{ \longmapsto{24 - 18 = {\boxed{6}}}}}}$

Difference of two numbers is 6, so option (3) is correct.

47.

If rag have pays an interest of ₹850 for 2 year on a sum of ₹ 6500, find the rate of interest

Answer»

en

Principal=₹ 6500
Time= 2 year
Simple INTEREST= ₹ 850

To Find

Rate =?

Formula

$\: \: \: \: \: \: \: \: \: \boxed{ \gray{ \sf SI= \dfrac{Principal× Rate×time}{100}}}$

Solution

Principal=₹ 6500
Time= 2 year
Simple Interest= ₹ 850

On Subtuting The VALUE in Formula

$\implies \sf \: 850= \dfrac{6500× Rate×2}{100}$

$\implies\sf \dfrac{85000}{6500 \times 2}= Rate$

$\implies\sf \sf \: \dfrac{425}{65 }= Rate$

$~~~~~~~~\sf Rate = 6.5$
