Question:-
Option (A)
8 : 30 a.m.
Option (B)
8 : 20 a.m.
Option (C)
8 : 25 a.m.
Option (D)
8 : 15 a.m.
Correct Option:
D
Question Solution:
100x – 85x = 5
15x = 5
x = (1/3)hrs = 20 min s
Required time = 7:55am + 20 mins = 8:15 am
Question:-
Option (A)
if a > b
Option (B)
if a < b
Option (C)
if a = b
Option (D)
if a ³ b
Correct Option:
C
Question Solution:
I ® (a – 5)2 = 0, i.e. a = 5
II ® 1.8 + 3.2 = b, i.e. b = 5 Thus, a = b
Question:-
Option (A)
14R
Option (B)
7R
Option (C)
(7/2)R
Option (D)
(R/2)
Correct Option:
C
Question Solution:
Let incomes be 7x and 5x and expenditures be 3y and 2y

Question:-
Option (A)
2/5
Option (B)
-4
Option (C)
-(4/3)
Option (D)
(2/3)
Correct Option:
C
Question Solution:
Put x = - a ® (-a)3 + a(-a)2 + - 2(-a) + a + 4 = 0
i.e. a = -(4/3)
Question:-
Option (A)
4
Option (B)
1
Option (C)
0
Option (D)
2
Correct Option:
D
Question Solution:
(20 / (8 + x)) = (12 / (8 - x))
-32x = - 64
x = 2 km/hr
Question:-
Option (A)
15, 8
Option (B)
30, 16
Option (C)
45, 24
Option (D)
60, 32
Correct Option:
D
Question Solution:
Let the ages be 15x and 8x
{(15x + 10) / (8x + 10)} = (5/3), i.e. 5x = 20, or x = 4
R = 15x = 60 and D = 8x = 32
