 A) 22 B) 23 C) 24 D) can't be determined

Explanation:

M is 8th from the top.

H is (50 - 20 + 1 =) 31 st from the top.

$\inline \therefore$ Number of students between M and H = (31 - 8- 1=)22

Q:

P, Q, R, S, T, U, V and W are sitting round the circle and are facing the centre:
P is second to the right of T who is the neighbour of R and V.
S is not the neighbour of P.
V is the neighbour of U.
Q is not between S and W. W is not between U and S.

Then Who is sitting opposite to U ?

 A) Q B) P C) R D) W

Explanation:

From the given information, the sitting arrangement can be

P-Q-W-S-U-V-T-R  i.e. in circular as

From the above figure it is clear that opposite to U is P.

Q:

A person is asked to put in a basket one apple when ordered 'one', one guava when ordered 'two', one orange whe ordered 'three' and is asked to take out from the basket one apple and one guava both when ordered 'four'. The ordered sequence executed by the person is as follows :

1 2 3 3 2 1 4 2 3 1 4 2 2 3 3 1 4 1 1 3 2 3 4

1. How many apples will be there in the basket at the end of the above order sequence ?
(a) 4     (b) 3     (c) 2    (d) 1

2. How many fruits will be there in the basket at the end of the above order sequence ?
(a) 13   (b) 17   (c) 9    (d) 11

Each time we order 1, one apple is added to the basket but each time when 4 is ordered, one apple is removed from it.

Required number of apples = number of 1's - number of 4's = 6 - 4 = 2

Each time we order 1, 2 or 3, one fruit is added to the basket but when ever we order 4, two fruits are removed from it.

Required number = Number of 1's + Number of 2's + Number of 3's - 2 x (Number of 4's)

= 6 + 6 + 7 - (2x4)
= 19 - 8
= 11.

Q:

In the series given below , how many 8's are there each of which is exactly divisible by its immediate preceeding as well as succeeding numbers ?
2 8 3 8 2 4 8 2 4 8 6 8 2 8 2 4 8 3 8 2 8 6

 A) five B) four C) two D) one

Explanation:

Clearly, we may mark such sets of 3 numbers, in which the middle number is 8 and each of the two numbers on both sides of it is a factor of 8, as shown below :

2 8 3 8 2 4 8 2 4 8 6 8 2 8 2 4 8 3 8 2 8 6

So, there are two such 8's. Hence the answer is C.

Q:

Vishal is 24th from either end of the row of boys ? How many boys are there in the row ?

 A) 48 B) 49 C) 46 D) 47

Explanation:

Given that Vishal is 24th from either end of the row i.e from two sides

1 2 3 4 5 . . . . . .24 23 22 21 20 . . . . . 5 4 3 2 1

Here before Vishal there are 23 members and after Vishal there are 23 members

= 23+1+23 $\Rightarrow$ 47 members in the row.
