Question

if 4.5 uniform weight 17.1 kg, what is the weight of 12 m rod​

Answer 1

Correct question:

• If 4.5 uniform rod weight 17.1 kg, What is the weight of 12 m rod?

Answer:

• The weight of 12 m of a uniform rod weighs 45.6kg.

Given:

• 4.5m uniform rod weights = 17.1 kg.

To find:

• What will be the weight of 12m of a uniform rod?

Solution:

4.5 of a uniform rod = 17.1 kg

Let the weight of 12m of a uniform rod be x

Let's do this in proportion method :

According to the question,

$\rightarrow \sf 4:5::17.1:12:x$

• Product of means = Product of extremes.

$\rightarrow \sf 4.5 \times x = 17.1 \times 12$

$\rightarrow \sf x = \dfrac{17.1 \times 12}{4.5}$

$\rightarrow \sf x = \dfrac{17.1 \times 12}{4.5}$

$\rightarrow \sf x = \dfrac{205.2}{4.5}$

$\rightarrow \sf x = {\cancel{\dfrac{205.2}{4.5} }}$

$\rightarrow \sf x = 45.6kg$

Hence, the weight of 12 m of a uniform rod weighs 45.6kg.

Appropriate Question

If 4.5 uniform rod weight 17.1 kg, What is the weight of 12 m rod ?⠀⠀⠀⠀⠀

Required Answer

The weight of 12 m of a uniform rod is 45.6 kg.⠀⠀⠀⠀⠀

Given:-

➢ 4.5 uniforms weight is 17.1 kg.

To Find:-

➢ What will be the weight of 12 m rod ?

Solution:-

➢ Weight of 4.5 m rod = 17.1 kg

➢ Weight of 1 m rod.

$\sf{ = \frac{ 17.1}{4.5}}kg$

➢ Weight of 12 m rod.

$\sf{ = \frac{ 17.1}{4.5}}kg$×12

= 45.6 kg

Hence,the weight of 12 m of a uniform rod is 45.6 kg.
