I think the correct answer is C.

In each number, the sum of the digits is either 11 or 14 except 331.

I also think the odd one out is 331 as 3 + 3 + 1 = 7 which is not equal to 11 or 14. As for all the other numbers, the sum of digits is 11 or 14.

The another way to solve this one with different answers like, '

3+3+1 = 7,
4+8+2 = 14,
5+5+1 = 11,
2+6+3 = 11,
3+8+3 = 14,
3+6+2 = 11,
2+8+4 =`14.
Hence, the sum of 331 is a single-digit number.

331 = taking the first number 3 and multiplying it with the third number 1 which means 3*1, the answer is 3 which is the middle number.

383 = 3*3, the answer is 9 but, the middle number is 8.

So the answer is option ā€˜C’.

3 + 3 + 1=7.
4 + 8 + 2=14.
5 + 5 + 1=11.
2 + 6 + 3 = 11.
3 + 8 + 3 = 14.
3 + 6 + 2 = 11.
2 + 8 + 4 = 14.

Thus 7 is a different and also a single digit number than 11 & 14.

Hence option 3 is correct.

Here the Formula is : First digit * Third digit = Middle digit.

331 = 3 * 1 = 3
482 = 4 * 2 = 8
551 = 5 * 1 = 5
263 = 2 * 3 = 6
383 = 3 * 3 = 6, so, hear formula goes Wrong
362 = 3 * 2 = 6
284 =2 * 4 = 8
So, the Answer is B i.e 383.

The product of all 3 digits is a perfect square except the product of 3*8*3.

Like;

3 * 3 * 1 = 9
4 * 8 * 2 = 64
5 * 5 * 1 = 25
2 * 6 * 3 = 36
3 * 6 * 2 = 36
2 * 8 * 4 = 64.
But
3 * 8 * 3 = 72
