If we consider (022, 033, 066, 099, 121, 279, 594) , then we see middle term sum of (1st & 3rd) term. Except 279.

11*2=22.

11*3=33.

11*6=66.

11*9=99.

11*11=121.

11*54=594.

279 is not divided by 11.

Is there any reason to multiply with 11?

If we multiply with 3 means the answer is 121.

Don't confused if add 1st and 3rd number we get middle number. So 279 is except from that then answer is 279.

Very nice.

From 3rd no, every number is three times previous-to-previous number.

Eg: 66 is thrice 22, 99 is thrice 33.

So, answer could also be 121 (198 should come instead).

But if u do like this :

22 * 3 = 66,
33 * 3 = 99,
66 * 3 = 198 but in problem 121 (Ans),
198 * 3 = 594,
99 * 3 = 279.

11, 33, 36, 108, 110, 333.

Find the odd man out.

Mahesh said:   8 years ago
Answer is 11.

33 = 3*11
36= 3*12
108= 3*36
110=11*10
333=3*111.

Only 11 is a prime number.

The simple solution is;

11*2=22,
11*3=33,
11*6=66,
11*9=99,
11*11=121,
11*54=594.

(eg:11*54= 594(take the middle number out (5-*9*-4)of any three digit answer then you can find the same number which is multiplied by the number 11)).

the same way other can be done.
