Question 10
Arnav's birthday is on Tuesday 14th March. On what day of the week will be Pranay's Birthday in the same year if Pranay was born on 13th September?
Solution
According to the question, 14th March is Tuesday
Number of days left in March = $$31-14=17$$
Similarly, odd days from 14th March till 13th September = $$(17+30+31+30+31+31+13)\%7$$
= $$3+2+3+2+3+3+6=22$$
Now, dividing 22 by 7, remainder = 1
Thus, day on 13th September = Tuesday (+1) = Wednesday
=> Ans - (C)
