Tough and Tricky questions: Combinations.



On Tuesday, Kramer purchases exactly 3 new shirts, 2 new sweaters, and 4 new hats, On the following day and each subsequent day thereafter, Kramer wears one of his new shirts together with one of his new sweaters and one of his new hats. Kramer avoids wearing the exact same combination of shirt, sweater, and hat for as long as possible. On which day is this no longer possible?

A. Tuesday
B. Wednesday
C. Thursday
D. Friday
E. Saturday

3 Shirts * 2 Sweaters * 4 Hats = 24 different combinations

Starting from Wednesday we have

W-T-F-Sa-Su-M-T = 7 days * 3 = 21 days (21st day will be Tuesday)

Next 3 remaining days : W - T - F

This means on Saturday combination will be repeated.
