Question

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

Answer 1

Answer:

3:1 is the correct answer

Step-by-step explanation:

x:y :: 6:5

Let common ratio be p.

So, 6:5 = 6p:5p.

x = 6p

y = 5p.

Now,

(5x+3y):(5x-3y)

Putting values of x and y..

(5 X 6p +3 X 5p):(5 X 6p - 3 X 5p)

= (30p + 15p):(30p - 15p)

= (45p) : (15p)

= 3:1
