Find the odd one out of the four options given below:
Options
Option A
(–3, –6)
Option B
(+1, –10)
Option C
(–2, –7)
Option D is correct
(–4, –9)
Explanation
All of these pairs i.e. (–3, –6); (+1, –10); (–2, –7) give same answer on adding, whereas – 4 + (–9) = –13, gives a different answer. So, odd one out is (–4, –9).
