SOLUTIONS:

Option D
Solution:
3x2– 2x – 8 = 0
3x2– 6x + 4x – 8 = 0
So x = -4/3, 2
6y2– 17y + 10 = 0
6y2– 12y – 5y + 10 = 0
So y = 5/6, 2
Put all values on number line and analyze the relationship
-4/3… 2… 5/6

Option E
Solution:
3x2+ 11x + 6 = 0
3x2+ 9x + 2x + 6 = 0
So x = -3, -2/3
5y2+ 16y + 3 = 0
5y2+ 15y + y + 3 = 0
So y = -1/5, -3
Put all values on number line and analyze the relationship
-3 …. -2/3 ….-1/5
Since the common value (-3) is not in between other 2 values, there is no
relationship between x and y.

Option E
Solution:
4x2– 11x + 6 = 0
4x2– 8x – 3x + 6 = 0
So x = 3/4, 2
6y2– 29y + 28 = 0
6y2– 8y – 21y + 28 = 0
So y = 4/3, 7/2
Put all values on number line and analyze the relationship
3/4 …. 4/3….. 2…. 7/2

Option C
Solution:
3x2– 25x + 52 = 0
3x2– 12x – 13x + 52 = 0
So x = 4, 13/3
3y2– 8y – 16 = 0
3y2– 12y + 4y – 16 = 0
So y = 4, -4/3
Put all values on number line and analyze the relationship
-4/3 …. 4…. 13/3

Option A
Solution:
8x2+ 10x + 3 = 0
8x2+ 4x + 6x + 3 = 0
So x = -3/4, -1/2
3y2+ 70y + 40 = 0
3y2+ 30y + 40y + 40 = 0
So y = -10, -4/3
Put all values on number line and analyze the relationship
-10 … -4/3 …. -3/4 …. -1/2

Option C
Solution:
Area of hall = 23*29 = 667 m2
Area of Manager room = 221 m2
, of pantry= 182 m2
Area of record room = 273 m2
Area of locker room = 609 m2
Total area to be floored with marble = locker area + record keeping + pantry = 182
+ 273 + 609 = 1064
So cost = 190*1064
Total area to be floored with marble = 221 + 667 = 888
So cost = 170*888
So required ratio = 170*888 : 190*1064 = 1887 : 2527

Option D
Solution:
Manager room flooring cost = 170 * 221 = Rs 37570
So cost of painting = [ 2 (12*17 + 12*13) + 17*13] * 190
= Rs 178790
So required total = 178790 + 37570 = Rs 216360

8)Option B
Solution:
Total area including all rooms = 2000 m2
Total area to be floored = 1952 = sq m
So remaining area = 2000 – 1952 = 48
So increased cost = 48*100 = Rs 5280

Option E
Solution:
Area not to be renovated = 48 m2
So required % = 48/2000 * 100 = 2.4%

10)Option D
Solution:
Cost of hall + locker area = 170 * 667 + 190*609= Rs 229100

Option A
Solution:
I : Mp =Rs 10,000; SP after 4% discount = Rs 9600; CP = Rs 8000
II : SP= 10,000*90/100 * 85/100 = Rs 7650
Hence I > I

Option A
Solution:
I: SI = 6200*6*5/100 = Rs 1860
II: CI = 6400 [1 – 5/100]<sup>2</sup> – 6400 = Rs 1376
Hence I > II

Option E
Solution:
I: Let CP = Rs 100, then at 10% loss, SP = Rs 90
Now if CP is 20% less, means CP = Rs 80, then profit is = 90 – 80 = Rs 10
but given profit is Rs 12
So if profit is Rs 10, then CP = Rs100
If profit is Rs 12, then CP is 100/10 * 12 = Rs 120
II: Use formula MP = (100-loss%)/(100-dicount%) * CPS
So MP = (100-20)/(100-30) * 105 = Rs 120
Hence I = II

Option C
Solution:
I: Since x < 0, so I will always be negative
II: It will be always positive
Hence I < II
