Question

5 m - n =3m +4n तर पुढील राशीच्या किमती काढा: $\frac{3m+4n}{3m-4n}$

Answer 1

Solution :

Given 5m-n = 3m + 4n

=> 5m - 3m = 4n + n

=> 2m = 5n

=> m/n = 5/2

m : n = 5 : 2

Let m = 5x , n = 2x

Now ,

$\frac{3m+4n}{3m-4n}$

= $\frac{3\cdot5x+4\cdot2x}{3\cdot5x-4\cdot2x}$

=$\frac{15x+8x}{15x-8x}$

= $\frac{23x}{7x}$

= $\frac{23}{7}$
