Answer» Correct Answer - Option 3 : 29 : 22 Given: x : y = 5 : 2. Calculation: Let the value of x and y be 5a and 2a respectively. According to the question, (8x + 9y) : (8x + 2y) ⇒ (8x + 9y)/(8x + 2y) ⇒ (8(5a) + 9(2a))/(8(5a) + 2(2a)) ⇒ (40a + 18a)/(40a + 4a) ⇒ 58a/44a ⇒ 29/22. ∴ The value of (8x + 9y) : (8x + 2y) is 29 : 22. |
