21. January 1,
1995 was Sunday. What day of the week lies on January 1, 1996?

(A) Sunday (B) Monday

(C) Saturday (D) None of these

Answer: B

**Explanation:**

Leap year is a year, occurring once every four years, which has 366 days
instead of the normal 365 days. The extra day is added in February, which has
29 days instead of the normal 28 days.

**Exception:**Century years are NOT leap years UNLESS they can be evenly divided by 400. For example, 1700, 1800, and 1900 were not leap years, but 1600 and 2000 were.

**Counting odd days and calculating day of any particular date:**

1 ordinary year = 365 days = (52 weeks + 1 day)

Hence number of odd days in 1 ordinary year = 1.

1 leap year = 366 days = (52 weeks + 2 days)

Hence number of odd days in 1 leap year= 2.

100 years = (76 ordinary years + 24 leap years ) = (76 x 1 + 24 x 2) odd
days

= 124 odd days. = (17 weeks + 5 days) = 5 odd days.

Hence number of odd days in 100 years = 5

Number of odd days in 200 years = (5 x 2) = 10 = 3

Number of odd days in 300 years = (5 x 3) = 15 = 1

Number of odd days in 400 years = (5 x 4 + 1) = 21 = 0

0 odd days Sunday

1 odd days Monday

2 odd days Tuesday

3 odd days Wednesday

4 odd days Thursday

5 odd days Friday

6 odd days Saturday

Here, 1995 is a normal year. It has one odd day. So the first day of
1996 will be Monday.

22. The sum of a
positive number and its reciprocal is twice the difference of the number and
its reciprocal. The number is :

(A) √2 (B) 1/√2

(C) √3 (D) 1/√3

Answer: C

**Explanation:**

Let the number be x. Its reciprocal is 1/x.

We are given, x+1/x = 2(x-1/x)

⇒ (x

^{2}+1)/x = 2(x^{2}-1)/x ⇒ (x^{2}+1) = 2(x^{2}-1) ⇒ -x^{2}= -3 ⇒ x^{2}= 3 ⇒ x = √3
