A) 221 B) 165
C) 35 D) 77
 
Answer & Explanation Answer: B) 165

Explanation:

The terms of the series are products of two consecutive prime numbers i.e.

So, 165 is wrong and must be replaced by (11 x 13) i.e. 143.

Q:

What was the day of the week on 28th May, 2006?

A) Sunday B) Friday
C) Wednesday D) Tuesday
 
Answer & Explanation Answer: A) Sunday

Explanation:

28 May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)

 

Odd days in 1600 years = 0

 

Odd days in 400 years = 0

 

5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) = 6 odd days

 

(31[jan] + 28 [Feb]+ 31[Mar] + 30[April] + 28[May] ) = 148 dayss = (21 weeks + 1 day) = 1 odd day.

 

Total number of odd days = (0 + 0 + 6 + 1) = 7 = 0 odd days.

 

Given day is Sunday

Q:

At what time between 2 and 3 o'clock will the hands of a clock be together?

A) (9 + 10/11) min past 2 B) (10 + 10/11) min past 2
C) (11 + 10/11) min past 2 D) (12 + 10/11) min past 2
 
Answer & Explanation Answer: B) (10 + 10/11) min past 2

Explanation:

At 2 o'clock, the hour hand is at 2 and the minute hand is at 12, i.e. they are 10 min spaces apart. 

 

To be together, the minute hand must gain 10 minutes over the hour hand. 

 

Now, 55 minutes are gained by it in 60 min.

 

  10 minutes will be gained in 6055×10 min. = 101011 min. 

 

The hands will coincide at 101011 min. past 2.
