Three of the numbers are alike in a certain way and one is different. Select the number that is different.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 119
Three of the numbers are multiples of 19: 133 = 19 × 7, 209 = 19 × 11 and 247 = 19 × 13.
119 is 7 × 17 and is not divisible by 19, so it is the odd one out.
