Question

1m cotton ka price 40 rupees
hai.
Aur 1m silk ka price
70 hai.
Aapke paas 5400 rupees ke
kapde hai.
Aur aapke paas jitne
length ka silk hai uske
double length ka
cotton hai.
(Yaani agar 5m silk
hai, toh 10m cotton
hogi)​

Answer 1

Concept:

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Given:

1m cotton ka price 40 rupees hai. Aur 1m silk ka price 70 hai. Aapke paas 5400 rupees ke kapde hai. Aur aapke paas jitne length ka silk hai uske double length ka cotton hai.

Find:

The lengthof silk and cotton

Solution:

Let the length of silk be x

So, the length of cotton be 2x

As per question,

70x+40.2x=5400

150x=5400

x= 36m

Therefore, the length of silk is 36m and length of cotton is 72 m

Step-by-step explanation:

A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation.

Given:

1m cotton ka price 40 rupees hai. Aur 1m silk ka price 70 hai. Aapke paas 5400 rupees ke kapde hai. Aur aapke paas jitne length ka silk hai uske double length ka cotton hai.

The lengthof silk and cotton

Let the length of silk be x

So, the length of cotton be 2x

As per question,

70x+40.2x=5400

150x=5400

x= 36m

Therefore, the length of silk is 36m and length of cotton is 72 m

1m cotton ka price 110₹ hai.

Aur 1m silk ka price 60₹ hai.

Aapke paas 5780₹ ke kapde hai.

Aur aapke paas same length ki cotton

and aur silk ka kapda hai.

Batayie aapke paas kitne metre cotton hai?​
