1.    (2)
A*(90/100) = (B*30)/100
= A x 3 = B
= A x x% = A x 3 = (x/100) = 3
x = 300

2.     (3)
Required percentage  = (40*100+50*90+60*80)/(40+50+60) = 88.66%

3.    (1)
Let y be 100
x = 75
Required percent  = (25*100)/75 = 33.33%

4.    (4)
Fourth number = (4x4+4x4 – 3x7)
= (16 + 16-21) = 11

5.    (3)
If the smallest number be x, then
(x/3)+12 = x+2
x + 36 = 3x + 6
3x -  x  = 36-6
2x = 30
x =15
third number = 15 + 4 = 19

6.    (1)

7.    (3)
Speed of the first train = 120/10 = 12 m/sec.
Speed of the second train =120/15= 8 m/sec.
Relative speed = (12 + 8) = 20 m/sec.
Therefore Required time =(120 + 120)/20  = 12 sec.

8.    (1)
Let Arun's weight by X kg.
According to Arun, 65 < X < 72
According to Arun's brother, 60 < X < 70.\
According to Arun's mother, X <= 68
The values satisfying all the above conditions are 66, 67 and 68.
Required average = 66 + 67 + 68/3 = 201/3   = 67 kg.

9.    (4)
L.C.M. of 252, 308 and 198 = 2772.
So, A, B and C will again meet at the starting point in 2772 sec. i.e., 46 min. 12 sec.
