If 5x+3yover 5x-3y= 7over3, then find x : y.

If ${5x+3y\over 5x-3y}= {7\over3},$ then find x : y.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 3 : 2.

According to the given question,

${5x+3y\over 5x-3y}= {7\over3}$

⇒ 3(5x + 3y) = 7(5x - 3y)

⇒ 15x + 9y = 35x - 21y

⇒ 20x = 30y

⇒ x : y = 3 : 2

Hence the value of x : y is 3 : 2.
