Question

Akshat is 10 weeks and 12 days older than me, whereas Jashn is 46 weeks and 13 days older than Akshat. If Jashn was born on a Tuesday, on which day of the week was I born?

A

Saturday.

B

Thursday.

C

Sunday.

D

Wednesday.

Soln.
Ans: a

Jashn is 10 + 46 = 56 weeks and 12 + 13 = 25 days older than me. Weeks are in multiples of 7 days. So we can ignore them. We can deal with the 25 days alone. Since 25 = 3 X 7 + 4, the excess days are 4. So we can count the day to Tuesday + 4 = Saturday.
