Today is Monday. After 61 days, it will be :

  • A.Tuesday
  • B.Monday
  • C.Sunday
  • D.Saturday

Answer: D

Only the remainder on division by 7 matters - the odd days.

\[ 61 = 8 \times 7 + 5 \quad\Longrightarrow\quad 5 \text{ odd days} \]

Counting five days on from Monday:

\[ \text{Tue, Wed, Thu, Fri, } \mathbf{Sat} \]

The eight complete weeks return to Monday and contribute nothing.
