Yes, every number is divisible by 11 but expect 279.

All numbers except 121 are divisible by 3.

So, 121 is also odd man out. Not denying the multiples of 11 logic. But both 121 or 279 must be the correct answer.

@Kartika answer will be 110.

11*3=33.

33+3=36.

36*3=108.

108+3=111(110 which is wrong).

111*3=333.

11*3=33.

33+3=36.

36*3=108.

108+3=111(110 which is wrong).

111*3=333.

11*2=22.

11*3=33.

11*6=66.

11*9=99.

11*11=121.

11*54=594.

279 is not divided by 11.

11*3=33.

11*6=66.

11*9=99.

11*11=121.

11*54=594.

279 is not divided by 11.

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.

11*2=22,

11*3=33,

11*6=66,

11*9=99,

Answer is 11.

33 = 3*11

36= 3*12

108= 3*36

110=11*10

333=3*111.

Only 11 is a prime number.

33 = 3*11

36= 3*12

108= 3*36

110=11*10

333=3*111.

Only 11 is a prime number.

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.

22 * 3 = 66,

33 * 3 = 99,

66 * 3 = 198 but in problem 121 (Ans),

198 * 3 = 594,

99 * 3 = 279.

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).

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

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