1( C)Explanation :28th May 2006 = (2005 years + period from 1-Jan-2006 to 28-May-2006)
We know that number of odd days in 400 years = 0
Hence the number of odd days in 2000 years = 0 (Since 2000 is a perfect multiple of 400)
Number of odd days in the period 2001-2005
= 4 normal years + 1 leap year
= 4 x 1 + 1 x 2 = 6
Days from 1-Jan-2006 to 28-May-2006 = 31 (Jan) + 28 (Feb) + 31 (Mar) + 30 (Apr) + 28(may)
= 148
148 days = 21 weeks + 1 day = 1 odd day
Total number of odd days = (0 + 6 + 1) = 7 odd days = 0 odd day
0 odd day = Sunday
Hence May 28 2006 is Sunday.

2.( C)Explanation :Let capacity of bucket P = x
Then capacity of bucket Q = x/3
Given that it takes 80 turns for bucket P to fill the empty drum
=> capacity of the drum = 80x
Number of turns required if both P and Q are used = (80x)/(x+x/3)
=240x/3x+x = 240/4=60

3.( D)Explanation :Given that January 1, 2007 was Monday.
Odd days in 2007 = 1 (we have taken the complete year 2007 because we need to find out
the odd days from 01-Jan-2007 to 31-Dec-2007, that is the whole year 2007)
Hence January 1, 2008 = (Monday + 1 Odd day) = Tuesday

4.( C)Explanation :Since pipe B is faster than pipe A, the tank will be emptied.
Part filled by pipe A in 1 minute = 1/12
Part emptied by pipe B in 1 minute = 1/6
Net part emptied by pipe A and pipe B in 1 minute = 1/6-1/12=1/12
Time taken to empty 2/5 of the tank = (2/5)/(1/12)=2×12/5=4.8 min

5. (B)Explanation:Perimeter = Distance covered in 8 min
. = (12000/60x 8)m = 1600 m.
Let length = 3x metres and breadth = 2x metres.
Then, 2(3x + 2x) = 1600 or  x = 160.
Length = 480 m and  Breadth = 320 m.
Area = (480 x 320) meter square = 153600 meter square

6.(D)Explanation :Let the principal = Rs.x
and time = y years
Principal,x amounts to Rs.400 at 10% per annum in y years
Simple Interest = (400-x)
Simple Interest = PRT/100
(400-x)=(x×10×y)100
(400-x)=xy/10— (equation 1)
Principal,x amounts to Rs.200 at 4% per annum in y years
Simple Interest = (200-x)
Simple Interest = PRT/100
(200-x)=x×4×y/100
(200-x)=xy/25 — (equation 2)
(equation 1)/(equation 2)?(400-x)/(200-x) =(xy/10)/(xy/25)
(400-x)/(200-x)=25/10
(400-x)/(200-x) =5/2
800-2x=1000-5x
200=3x
x=200/3
Substituting this value of x in Equation 1, we get,(400-200/3)=((200/3)y)/10
?(400-200/3)=20y/3
?1200-200=20y
?1000=20y
y=1000/20 =50 years

7.(B)Explanation:Area of the park = (60 x 40) m2 = 2400 m^2.
Area of the lawn = 2109 m^2.
Area of the crossroads = (2400 – 2109) m^2 = 291 m^2.
Let the width of the road be x metres. Then,
60x + 40x – x^2 = 291
= x^2 – 100x + 291 = 0
= (x – 97)(x – 3) = 0
= x = 3.

8.(D)Explanation:Area to be plastered= [2(l + b) x h] + (l x b)
= {[2(25 + 12) x 6] + (25 x 12)} m^2
= (444 + 300) m^2
= 744 m^2.
Cost of plastering = 744 x75/100 = Rs. 558.

9.( B)Explanation :We know that Angle traced by hour hand in 12 hrs = 360°
From 8 to 2, there are 6 hours
The angle traced by the hour hand in 6 hours = 6×360/12=180°

10.( D)Explanation:Let original length = a and original breadth = b
Decrease in area = ab – (80/100 a x 90/100 b)
= (ab-18/25ab)
=7/25ab.
So  Decrease % = (7/25 abx1/abx100)%= 28%
