Answer:
20th Dec Thursday
Step-by-step explanation:
Mr. X has three children the birth of the first chiled falls on the 5th monday of april, that of the second one falls on the 5th thursday of november. On which day is birth of his third chiled which falls on 20 th december
5th Monday of April can be
29th April or 30th April
Case 1 : 29th April Monday
then 1 + 31 + 30 + 31 + 31 + 30 + 31 + 1 = 186 Days = 26*7 + 4
=> 1 November = Friday
=> 29th , 30th Nov are Friday & Saturday
so no 5th Thursday
Case 2 : 30th April Monday
then 31 + 30 + 31 + 31 + 30 + 31 + 1 = 185 Days = 26*7 + 3
=> 1 November = Thursday
=> 29th Nov is 5th Thursday
=> 6th Dec is Thursday
6 + 2 * 7 = 20
=> 20th Dec id also Thursday (3rd Thursday of December)
20th Dec Thursday
