Explanation:

Let us first calculate the number of odd days after 15^th Aug, 1947 till 15^th Aug, 1949:

Odd days from
15^th Aug, 1947 - 15^th Aug, 1948 = 2 (because of 29^th Feb, 1948) 
15^th Aug, 1948 - 15^th Aug, 1949 = 1 

Total odd days = 2 + 1 = 3 odd days.

Now, let us calculate the odd days after 15^th Aug, 1949 till 26^th Jan, 1950.

Aug = 16
Sep = 30
Oct = 31
Nov = 30
Dec = 31
Jan = 26

∴ Total days = 16 + 30 + 31 + 30 + 31 + 26 = 164 day.

∴ Odd days = Remainder (164 ÷ 7) = 3.

⇒ Total odd days from 15^th Aug, 1947 till 26^th Jan, 1950 = 3 + 3 = 6.

∴ If it is Friday on 15^th Aug, 1947, day of the week on 26^th Jan, 1950 will be same as the day of the week 6 days after Friday i.e., Thursday.

Hence, option (a).
