Given,

The value of \[5\frac{2}{3}m\] rope is \[12\frac{3}{4}\] Rs.

Solution,

\[5\frac{2}{3}m\] rope's price\[=12\frac{3}{4}Rs.\]

or

\[\frac{{17}}{3}m\] rope's price\[ = \frac{{51}}{4}Rs.\]

\[1m\] rope's price,

\[ = \frac{{\frac{{51}}{4}}}{{\frac{{17}}{3}}}Rs.\]

\[ = \frac{{51 \times 3}}{{17 \times 4}}Rs.\]

\[ = \frac{{153}}{{68}}Rs.\]

\[ = 2\frac{{14}}{{68}}Rs.\]

Hence the price of 1 m rope is \[2\frac{{14}}{{68}}Rs.\]

Given : 5 2/3 मीटर रस्सी का मूल्य 12 3/4 रुपए है

To Find : रस्सी का प्रति मीटर मूल्य

Solution:

5 2/3 मीटर रस्सी   = (5 * 3 + 2)/3  = 17/3  मीटर रस्सी

मूल्य  12 3/4 रुपए = (12 * 4 + 3)/4  = 51/4  रुपए

रस्सी का प्रति मीटर मूल्य  =   x रुपए

=> 17/3  मीटर रस्सी का मूल्य  = 17x/3 रुपए

17x/3 =  51/4

=> x/3  = 3/4

=> x = 9/4

=>  x = 2 1/4  

रस्सी का प्रति मीटर मूल्य   2\dfrac{1}{4}  रुपए
