27 38 ?
(A) 49 (B) 50
(C) 51 (D) 52
plz answer all with detailed explanations




answer to the first question is (B) brother as vipul's grandfather's only son is his father and it's obvious that his father's daughter would be his sister and he would be her brother.Vipul is his brother

answer to the second question is (A) 49 as in the series 1+1=2 & 2+1= 3

similarly, in the last series first number is 27        2+1=3 & 7+1=8   so the second number is 38

similarly 3+1=4 & 8+1=9 so next number is 49..........

i think this explanation would be enough for you..........


Q1. The answer is (B) Brother. Vipul's grandfather's only son is his father and his daughter would be Vipul's sister. 

Q2. Answer is (A) 49  -In the last series second digits of the 27,38  are 2,3  and are in series hence the second digit of third no is 4 . Similarly the first digits are 7,8 and are in series .Hence the  first digit of the number is 9.Hence the number is 49.
