Answers:
1)a  2)e  3)c  4)e  5)e  6)c  7)e  8)d  9)a  10)b

Solution:
1). From (a), we notice that the number is of the form 8n+2, which means it also leaves a remainder 2 on being divided by 4. So, its not divisible by 12.
From (b) and (c) together, the number can be any multiple of 6, from which we cant conclusively say if number is divisible by 12.
Answer: a)

2). The fact that half scored above 700, and other half less than 700 does not tell the actual distribution of scores to calculate the average. Statement (c) also does not help us determine the average.
Answer: e)

3). Let C be the wholesale price, listed Price be P. from (a), P = 1.2C
From (b), 0.9P = C + 10. Using statement (a), 1.2C = C + 10, from this we can determine C.
From (C), we have sales price = C + 50. From this we cant determine C, even if we combine information from other statements.
So (a) and (b) together are sufficient to answer the question.
Answer: c)

4). We can have p = 0.45, and q = 0.41. here p>q
We can also have p = 0.45,and q = 10. Here p<q
So, we cant determine using both statements if p>q.
Answer: e)

5). Using (A), we can have ‘p’ as 2/4/6/8 etc. we cant determine remainder when divided by 3.
Using (B), we can have ‘p’ as 1/4/9/16 etc. we cant determine remainder when divided by 3.
Using both ‘p’ is the square of an even number. So ‘p’ can be 4/16/36 etc.
We see that remainder can again be 1/0 (4/16 leave remainder 1, 36 remainder 0).
So, we cant determine using both statements.
Answer: e)

6). 2xI – II = 6x – 5z = 12(IV)
IV – III = x – z = 1 or x = z + 1
Substituting in III, we get x = 7, z = 6
Putting x = 7 in I, we get y = 9
Hence x < y > z
Answer: c)

7). From II, y = 2.8
Putting in I, we get 2x + 14 = 19.6
= 2x = 5.6 or x = 2.8
Putting x = 2.8 in III, we get 28 – 7z = 8.4
= 7z = 19.6 or z = 2.8
Hence x = y = z
Answer: e)

8). III – 2xI = 3y + 6x = 28.5 or 2y + 4x = 19(IV)
II – IV = x = 3.5
Putting in I, z – 10.5 = -6
Z = 4.5
Putting in II, 17.5 + 2y = 22.5
Y = 2.5
Hence x > y < z
Answer: d)

9). From II, 3y = -2z + 15
From III, x = 3z -4
Putting in I, 3z – 4 – 2z + 15 – 7z = -7
= -6z + 11 = -7  
z = 3
Substituting in II and III, we get
x = 5, y =3
hence x > y = z
Answer: a)

10). From I, (x-7) (x-4) = 0
 x = 7,4
From II, (y-4) (y-3) = 0
 y = 4, 3
From III, (z-3) (z-1) = 0
z = 3, 1
hence x ≥ y ≥ z

Answer: b)
