If (7x + y) : (7x – y) = 7 : 3, then what is the value of x : y?

Answer

The correct answer is D: 5 : 14. Cross-multiplying: 3(7x+y)=7(7x–y) → 21x+3y=49x–7y → 10y=28x → x/y=10/28=5/14. So x:y = 5:14.

  1. A.6 : 15
  2. B.15 : 6
  3. C.4 : 3
  4. D.5 : 14✓ Correct

Explanation

Cross-multiplying: 3(7x+y)=7(7x–y) → 21x+3y=49x–7y → 10y=28x → x/y=10/28=5/14. So x:y = 5:14.
