I. P

– 6p + 8 = 0
P=  ( + 2,  + 4)
II. q
2
+ 11q + 10 = 0
q = (- 1, - 10)
Clearly, p > q

87. (2): I. p =
2809

P = 53
II. q
2
= 2809
q = ± 53
p = q
88. (3): 2p – 3q = – 3.5
2p – 3q + 3.5 = 0
II. 3p – 2q = – 6.5
3 x (2p – 3q = – 3.5)….(1)
2 x (3p – 2q = – 6.5………(2)
From Equation (1) and (2)
q = - 0.5 ,p = - 2.5
q  > p
89. (5): I. p
2
+ 8p + 15 = 0
p = ( – 3,  – 5)
II. q
2
+ 10q + 24 = 0
q = (– 4  , – 6)
Relationship cannot be determined.
90. (4): I. p
2
+ 28p + 192 = 0
p = ( – 12, – 16)
II. q
2
+ 16q + 48 = 0
q = (– 4, – 12)
p = q
91. (3) Let the number be X and Y
Then 6y – x = 71 and 7x + y = 62
Solving the equation
X = 7 , y = 13
92. (4) Let the present ages of Yug, Vinod and karan be
3x, 4x and 5x years respectively.
Now, (3x + 4x + 5x)/3 = 28 ?12x = 84?x = 84/12 = 7
So, required Sum = (3x + 4x + (5 + 5) years
= (7x+ 10) years
= (7 ×7 + 10) years
=59 years

95. (2) Number of questions attempted correctly =
70% of 10 + 50% of 30 + 60% of 45  = 7 + 15 + 27 =
49
Passing grade = (60/100 )* 85 = 51
Reqd.  Ans = 51 - 49 = 2
96. (1) First she faced loss of 12%
Now she left with 88% amount then again she have
gain of 12%
Then amount she have = (88*112)/100 = 98.56%
Loss% = 100 – 98.56 = 1.44%
Loss = 46000*1.44% = 662.4 Rs.
97. (5)  Let distance be D and speed of boat in still water =
x kmph
D = (x+3) 1 =x + 3 ……(1)
D  =(x – 3) 3/2  …………(2)
From eq (1) and (2)
X = 15 kmph
98. (1).  Marked price = 130%
Discount = 20%
S.P. = (130*80)/100% = 104%
Profit % = (104 – 100) = 4%
