Correct Answer: Thursday


Solution : Given:
5th May 1911 is Friday
11th September 1919 = ?

Let's calculate the total number of days –
1911→May = 31 – 5 = 26; June = 30; July = 31; Aug = 31; Sep = 30; Oct = 31; Nov = 30; Dec = 31
26 + 30 + 31 + 31 + 30 + 31 + 30 + 31 = 240
From 1912 to 1918→(7 × 365) + 2 = 2555 + 2 = 2557 (Extra 2 days are added as 1912 and 1916 are leap years.)
1919→Jan = 31; Feb = 28; March = 31; April = 30; May = 31; June = 30; July = 31; Aug = 31; Sep = 11
31 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 11 = 254

Total number of days→240 + 2557 + 254 = 3051
On, dividing 3031 by 7, we get 6 as a remainder. So, 6 days after Friday is Thursday.

So, 11th September 1919 will be Thursday. Hence, the fourth option is correct.
