Question

If 12th May of an ordinary, non-leap year falls on a Wednesday, then what will be the day of week on 18th August of that year?

A

Wednesday.

B

Sunday.

C

Monday.

D

Saturday.

Soln.
Ans: a

Count the days from months between May 12 and August 18 like this: May days = 31;June days = 30;July days = 31;Add 18 days of August. Subtract 12 days of May. So total days = 98. Since 98 = 14 X 7 + 0, so excess days are 0. So we can count the day to Wednesday + 0 = Wednesday.
