Answer 1

Answer:

I think Tuesday not sure

Answer 2

hey mate

first of all let us assume 2 names for them

let the first person be X

and second one be Y

                                        According to the question

X's birthday comes after 64 days of Y's birthday

hence to convert it into weeks

divide it by 7

but 64 isn't a perfect dividend for 7

hence nearest dividend to 64 which is divisible by 7 is 63

therefore

$64 days =63 days + 1 day \\=\frac{63}{7} weeks +1 day \\=9 \:weeks\: and\: 1\: day$

hence X birthday is 9 weeks and 1 day after y's birthady

assuming Y's birthday to be on 1st day of any month

and the being monday (given)

after 9 weeks, i.e, 1 day before X's birthday

the day will be monday

and on X's birthday the day will be

Tuesday
