BMonday

DFriday
Answer:
A. Wednesday
Read Explanation:
Solution:
17th June, 1998 = (1997 years + Period from 1 - 1 - 998 to 17 - 6 - 1998)
1) Odd days in 1600 years = 0
2) Odd days in 300 years = (5 × 3) = 1
97 years (1901 to 1997) has 24 leap years + 73 ordinary years.
3) Number of odd days in 97 years (24 × 2 + 73) = 121 = 2 odd days.
4) Number of odd days from 1 January 1998 to 17 June 1998 = 3 + 0 + 3 + 2 + 3 + 17 = 28/7 = 0
Total number of odd days = (0 + 1 + 2 + 0) = 3.
No. of odd days | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
Day of the week | Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
Therefore, he purchased his car on Wednesday.
Hence, Wednesday is the correct answer.
