(4) Thursday

Answer 1

Answer:

If 09/12/2001 happens to be Sunday, then 09/12/1971 would have been a

Thursday

Step-by-step explanation:

Every year day increase by 1 and if leap year come then by 2

=> leap year increase on day extra

2001 - 1971 = 30 years

so increase of 30 days

Leap years 1972 , 1976  , 1980 , 1984 , 1988 , 1992 , 1996 ( divisible by 4)  , 2000 (divisible by 400)

8 Leap years

Total days increase = 30 + 8 = 38 days

38 = 5*7 + 3

3 days increased from 09/12/1971 to  09/12/1971

so it would be Thursday on 09/12/1971   , if 09/12/1971 is sunday

Option 4 is correct
