Question

Anamika took 21 days leave from her office. When did she join the office again, if her leave started from ${{17}^{th}}$ December 2014?

Answer 1

Hint: It is given that the leave started from ${{17}^{th}}$ December 2014 and the number of days of the leave was 21 days. So, to find when she will be joining the office again, we have to calculate 21 days ahead from ${{17}^{th}}$ December and find the date when she joins the office again.

Complete step by step solution:
It is given in the question that Anamika took 21 days leave from her office and we have been asked to find when she would join the office again if she started her leave from ${{17}^{th}}$ December 2014. So, in order to find that we, will have to add 21 days from ${{17}^{th}}$ December 2014 to know the exact date she would be joining the office again. Now, if we look at the number of days in December, there are 31 days. We know her leave started from ${{17}^{th}}$ December. So, that means she worked till ${{16}^{th}}$ December. So, the number of days that are left in the month of December are 31 - 16 = 15 days. But as it is given that she has taken leave for 21 days, so we have 21 - 15 = 6 days more left to be added to her leave. So, we will add those 6 days in January 2015. So, she will join the office again after 6 days in January 2015, that is on ${{7}^{th}}$ January 2015.
Hence, she joined her office back after the leave on ${{7}^{th}}$ January 2015.

Note: The possible mistakes that students can make in this question are that they forget to add ${{17}^{th}}$ December in the number of days of the leave, but it is clearly given in the question that her leave started from ${{17}^{th}}$ December, which means that is the first day of her leave. Similarly, the students may forget to change the year from 2014 to 2015.
