1st day of month = Thursday, Tuesday of 1st week = day 6, Tuesday of 2nd week = 6+7 = day 13, Tuesday of 3rd week = 13+7 = day 20, Tuesday of 4th week = 20+7 = day 27 The answer is day 27.

by drawing a calendar with 1st on Thursday, it would be observed that the 4th Tuesday is 27.

1 is thursday . so first tuesday will be on 6 of month. +7 gives us the date of next tuesday bcoz a week contains 7 days so 6+7+7+7 =fourth Tuesday

so 27 =fourth tuesday

M T W T F S S 1 2 3 4 5 6 7 8 9 10 and goes on and we get 27

Simply look the calendar of August of this year,find the fourth Tuesday of the month.

"The first of the month falls on a Thursday". Which means Thursday be the $1^{st}$ date of the month, and the first Tuesday would be on $6^{th}$ , which makes the second Tuesday would be on $13^{th}$ , which makes the third Tuesday would be on $20^{th}$ , and the fourth Tuesday would be $27^{th}$ . Thus the answer is $27$

1+4x7-2=27
