Question

Rani birthday falls on 4th feb.1990.which day will fall on the day which is 47 days after her birthday if 4 feb. 1990 is sunday​

Answer 1

Given,

Rani's birthday falls on 4th february,1990.

To find,

The day which falls 47 days after the birthday of Rani.

Solution,

To easily solve this mathematical problem,we can use the fact that every day of the week is repeated after 7 days.

In this case,the initial day is sunday.

And,the multiple of 7 which is nearest to the days gap is 49.

So,after 49 days another sunday will fall.

But,the day gap is 2 less, so the final day will be 2 days before sunday.

Final = Sunday - 2 = Friday

Now,the year is not divisible by four,so it isn't a leap year.

The date of the final day = 23rd march

(24 days of February and 23 days of march)

Hence,the final day is a Friday and it's 23rd of march.
