Agree with above, 331 is also the only option, that when all digits are added, the answer is a single digit (meaning lower than 10).

Kumar M V said:   1 decade ago
Answer is 383. In the given list of numbers, if we divide 2nd and 3rd digit number it will produce the 1st digit number.

Ex:- 331= 3/1=3.
482= 8/2=4.
551= 5/1=5.
263= 6/3=2.
383= 8/3 for this number we don't get the first digit, when 2nd and 3rd numbers are divided.
362= 6/2=3.
284= 8/4=2.

Answer may be 331 also as all other numbers in the series has their digit's sum of either 11 or 14 except 331.

It is so easy @Rajesh multiply the end numbers of the 3 digit numbers so you get the mid value.

ex:

331 = 3*1 = 3(middle number).
482 = 4*2 = 8(middle number).

But,

338 = 3*8 = 24(wrong answer).

Another possible answer is 331. If we divide all the given number by 3 then remainder will be 2, except 331.

Can give a better explanation with other logic for same problem.

3*1=3 , 3(3)1 =331.

4*2=8 , 4(8)2 =482.

3*3=9 , 3(8)3 =383,

In each number except 383, the product of first and third digits is the middle one.

3 * 1 = 3 331.
4 * 2 = 8 482.
5 * 1 = 5 551.
2 * 3 = 6 263.
3 * 3 = 9 383 it is wrong.
3 * 2 = 6 362.
2 * 4 = 8 284.

Another Option:

If we divide each number by 3 then we get remainder 2 except in 331. So option 'c' is also odd man out.

Very simple... you know 331... 3 and 1=3 there middle value..3(3)1

Next find same 482....4*2=8 middle 4(8)2
551 5*1=5 middle 5(5)1
263 2*3=6 """ 2(6)3
383 3*3=9 there middle value not same 3(9)3.
