Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number-pair that is different from the rest.
Answer & explanation
Correct answer: option 2
THE LOGIC;
1) 6 - 174,
174 \(\div \) 6 = 29
2) 8 - 138,
138 \(\div \) 8 = 17.25
3) 5 - 155,
155 \(\div \) 5 = 31
4) 11 - 143,
143 \(\div \) 11 = 13
Thus, 8 - 138 is different from others.
