Day Calculation

The 4th of the month is a Tuesday.

Step 1: Find the day on the 24th of the month:

• 4th (Tuesday) → 11th (Tuesday + 7 days = 1 week)
• 11th → 18th (Tuesday + 7 days = 1 more week)
• 18th → 24th (Tuesday + 6 days = 6 days ahead, so 24th is a Monday)

Step 2: Now, calculate 3 days after the 24th (Monday):

• Monday → Tuesday (1 day)
• Tuesday → Wednesday (2 days)
• Wednesday → Thursday (3 days)

Answer: 3 days after the 24th is a Thursday.

Given:

• Raman was born on March 5, 1970.
• Lakshman was born 25 days before Raman.
• January 26, 1970 was a Monday.

Step 1: Calculate Lakshman's date of birth.

• Raman: March 5, 1970
• Subtract 25 days → Lakshman's DOB = February 8, 1970

Step 2: Find the day of the week for February 8, 1970

• We know January 26, 1970 = Monday
• From Jan 26 to Feb 8 = 13 days
• 13 % 7 = 6 → Add 6 days to Monday
• Monday + 6 days = Sunday → So February 1 = Sunday
• Then, February 8 = Sunday + 7 = next Sunday = Sunday

✅ Final Answer: Lakshman was born on Sunday, February 8, 1970
