Detailed Solution

We need to find the odd one out among the following:

− 5 11, − 1 2, − 4 9, − 7 3

.
Find the numbers which are greater than -1 and smaller than -1 from the list.

− 5 11

⇒

-1 can be written as

− 11 11

.
So, while comparing

− 5 11

and

− 11 11

− 5 11 > − 11 11 ⇒ − 5 11 > − 1

− 1 2

⇒

-1 can be written as

− 2 2

. Therefore,

− 1 2 > − 2 2 ⇒ − 1 2 > − 1

− 4 9

⇒

-1 can be written as

− 9 9

. So,

− 4 9 > − 9 9 ⇒ − 4 9 > − 1

− 7 3

⇒

-1 can be written as

− 3 3

. So,

− 7 3 < − 3 3 ⇒ − 7 3 < − 1

.
Therefore,

− 7 3

is the odd one, since it is the only number which is less than -1 among the other three numbers.
Hence, 4 is the correct option.
