Choose the number which is different from others in the groups?
751, 734, 981, 853, 532
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 751
In each number the first digit is compared with the sum of the other two digits.
734: \(3+4=7\), equal to the first digit
981: \(8+1=9\), equal to the first digit
853: \(5+3=8\), equal to the first digit
532: \(3+2=5\), equal to the first digit
751: \(5+1=6\), not 7
751 is the only number whose first digit is not the sum of the other two, so 751 is the odd one out.
