Question

8.75 m of cloth cost 490. Find the cost of 1 m of cloth.​

Answer 1

Answer:

Given

8.75m of cloth costs Rs 420

Can be written as

8.75 × 1 m = 420

1m = 42000/875

1m = Rs /- 48

Now Question says " find the cost of 3.5 m of the same cloth "

we will have to multiply it only

cost of 3.5 m = 3.5 × 48

= ( 7/2 ) × 48

= 24 × 7

= Rs /- 168

Answer 2

To find: cost of one meter of the cloth.

Given : $8.75$ m of cloth cost $490$.  

solution:

• We are given that cost of $8.75$ m of cloth is $Rs\ 490$. Let us find cost of $1 \mathrm{~m}$ cloth,
• Cost of $8.75 \mathrm{~m}=Rs \ 490$
• Hence cost of  $1 m=\frac{1 \times 490}{8.75}$
• To remove decimal we multiply numerator and denominator by $100$ .

        $1 m=\frac{490 \times 100}{8.75 \times 100}$

             $= \frac{49000}{875} \\= 56$  

Hence , cost of one meter of the cloth  is $Rs \ 56$ .
