Given :

October 1994

To find out :

On which dates did Monday fall ?

Solution :

1600 years have zero off days.

300 years contain one odd day.

93 years have 23 leap years and 70 non leap years .

total number of odd days in 93 years : (23 × 2 + 7 × 1 ) = 116 odd days⇒4 odd days.

From 1st January to 1 October number of odd days in 1994 .

Month : J + F + M + A + J + J + A + S + O

Odd days = 3 + 0 + 3 + 2 +3 +2 +3 +3 +2 +1 = 22 odd days ⇒1 odd day.

The total number of odd days = 1 +4 +1 =6 odd days.

1st October 1994 is Saturday so first Monday will fall on 3rd October .

hence 3, 10, 17, 24 and 31 October was Monday.

option ( D) is correct option.
