Answer:
3rd February was a Sunday.
Step-by-step explanation:
8th April is a Friday, so subtract 7 to get the date of the Friday before. Repeat this process:
8-7=1st April
February has 28 days in this year, because 2019 isn't a leap year. So:
1-7=22nd February
22-7=15th February
15-7=8th February
8-7=1st February
All these dates are Fridays. So if the 1st February is a Friday, the 2nd February is a Saturday, and the 3rd February is a Sunday.
