Calendar of 2013 is related to calendar of 2015 same as calendar of 1977 to which one of the following year?Question 39Answera.1990b.1985c.1991d.1981

The relationship between the calendars of 2013 and 2015 is that they are exactly the same, but shifted by two years. This is because both years are non-leap years and the day of the week on January 1 is two days later in 2015 than in 2013.

To find the year that has the same relationship to 1977, we need to find a non-leap year that is two years later. 1977 is a non-leap year, so we add two to get 1979.

However, 1979 is not one of the options given in the question. This suggests that there may be an error in the question or that it is based on a different calendar system.

Without additional information, it's not possible to give a definitive answer based on the options provided (1990, 1985, 1991, 1981).
