Q. 51. How many years have 29 days in February from 2001 to 2100?
(A) 26
(B) 25
(C) 23
(D) 24
Answer:
(D) 24
Explanation:
A leap year occurs every 4 years, but a century year is not a leap year unless it is divisible by 400. Therefore, the year 2100 is not a leap year. Between 2001 and 2100, there are exactly 24 leap years.
Q. 52. In 2012, January 1st is Sunday, then which day is the Indian Independence Day of the same year.

(A) 7
(B) 10
(C) 12
(D) 13
Answer:
(B) 10

Q. 54. Find the missing number in the series: 363, 275, 484, 891, …
(A) 393
(B) 582

Q. 55. Find the missing number in the series: 95, 115.5, 138, …
(A) 154.5
(B) 162.5
(C) 164.5
(D) 166.5
Answer:
(B) 162.5
Explanation:
The difference between consecutive terms increases by 2 each time. (115.5 – 95 = 20.5), (138 – 115.5 = 22.5). The next difference should be 24.5. Thus, 138 + 24.5 = 162.5.
