The average of 3 consecutive odd numbers is 65. What is the ratio of these numbers?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 63:65:67
Consecutive odd numbers are 2 apart, so three of them are evenly spaced and their average is the middle number.
Middle number \(=65\)
The numbers are \(65-2=63\), 65 and \(65+2=67\)
Their ratio is 63 : 65 : 67 (no common factor, so it does not reduce)
