Given : 2011 is an example of digit number exactly 2 digits are identical and adjacent number of 4 digit numbers with same property including 2011

To Find : Similar number from given options

1)1944 2)2439 3)2521 4)2440

Solution:

2011  -  1 is repeated  2 times

Adjacent

2010   - 0 is repeated    2 times

2012 -    2   is repeated   2 times

1944  -  4 is repeated  2 times

but 1943 and 1945 does not have any digit repeated

2439  Does not have any digit repeated

2521  - 2   is repeated   2 times

2520  -  2   is repeated  2 times

2522   - 2 is repeated 3 times   ( hence not possible)

2440  - 4 is repeated  2 times

2441  - 4  is repeated  2 times

2439  -  Does not have any digit repeated

Hence None of the given option satisfy the condition

Could be few examples:

2010   0  is repeated  2 times

Adjacent 2009    0  is repeated  2 times

and 2011        1  is repeated  2 times

 

2009

Adjacent 2008 and 2010    

Each have digit 0 repeated 2 times
