Question 41

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.

Solution

7 : 343 $$\longrightarrow\ $$ 7 : 7$$^3$$

11 : 1331 $$\longrightarrow\ $$ 11 : 11$$^3$$

3 : 27 $$\longrightarrow\ $$ 3 : 3$$^3$$

1757 is not the cube of 12

$$\therefore\ $$12 : 1757 is the odd one among the given number pairs

Hence, the correct answer is Option B
