Question

A 5 meter long copper wire cost RS 12.60.find the cost of 37 meter of such wire?

Answer 1

Answer:

₹93.24

Step-by-step explanation:

5 meter = 12.60

=> 1 meter = 12.60 / 5 = Rupees 2.52

Therefore 37 meter of wire = 2.52 x 37 = Rupees 93.24

${\large{\tt{\underline{\maltese \: \: Undertanding \; the \; Question...}}}}$

In this problem, the concept of unitary method is used. In this method, the main idea is that we need to find the value of single unit first. At next, we will multiply the required value with the single unit. Let's solve it!!

${\large{\tt{\underline{\maltese \: \: Given \; that...}}}}$

• 5m long copper wire cost Rs.12.60.

${\large{\tt{\underline{\maltese \: \: To \; find...}}}}$

• Cost of 37m long copper wire.

${\large{\tt{\underline{\maltese \: \: Solution:}}}}$

${\tt{:\implies Cost\:of\:5m\:wire \: = 12.60}}$

Finding the value of single unit;

${\tt{:\implies Cost\:of\:1m\:wire \: = \dfrac{12.60}{5}}}$

${\tt{:\implies Cost\:of\:1m\:wire \: = Rs.2.52}}$

Now, we are going to multiply 37 with the cost of 1m wire (single unit), since we need to find the cost of 37m long copper wire.

${\tt{:\implies Cost\:of\:37m\:wire \: = Cost\:of\:1m\:wire \times 37}}$

${\tt{:\implies Cost\:of\:37m\:wire \: = 2.52 \times 37}}$

${\tt{:\implies Cost\:of\:37m\:wire \: = Rs.93.24}}$

${\underline{\frak{Therefore, \: Cost\:of\:37m\:wire\:is\:Rs.93.24.}}}$
