उत्तर

Monday

Explanation:

We know that,  
Number of odd days in a non-leap year = 1  
Number of odd days in a Leap year = 2  
As year 1976 is a leap year.  
So, Number of odd day in 1976 = 2  
Similarly, 1980, 1984 are two leap year.  
between 1976 to 1986  
Also, Number of non-leap year between 1976 to 1986  = 7 year  
Total number of odd days  
= 3 × 2 + 7 × 1 = 13 days  
13 days = 1 week + 6 days  
Hence, 13th January 1986 will be Monday.
