Question

If x : y = 6 : 5, then (5x+3y) : (5x-3y) is equal to……

Answer 1

Answer:

3:1

Step-by-step explanation:

Answer 2

$\frac{x}{y} = \frac{6}{5} \\ 5x = 6y \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: .... \: (i)$

now,

$\: \: \: \frac{5x + 3y}{5x - 3y} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ... \: (from \: i)\\ = \frac{6y + 3y}{6y - 3y} \ = \frac{9y}{3y} = \frac{3}{1}$

= 3:1
