Answer» Correct Answer - Option 2 : 33 Given: The ratio of three numbers = 5 ∶ 9 ∶ 11 The second number is greater than the average of first and third number by 3 Concept used: Average = (Total sum)/(Total numbers) Calculations: Let the numbers be 5x, 9x, and 11x respectively Average of first and third number = (5x + 11x)/2 = 8x According to question ⇒ 9x = 8x + 3 ⇒ x = 3 The largest number = 11x ⇒ 11 × 3 = 33 ∴ The largest number is 33 |
