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)
