If it is possible to form a number which is a perfect square of a two digit odd number using the second, fourth, seventh digits of the number 739142658 using each only once, which of the following is the second digit of that two-digit odd number?
Answer: D
Correct answer: none
The second, fourth and seventh digits of 739142658 are 3, 1 and 6. Arranged as 361 they do make \( 19^2 \), so such a number can be formed - but the digit the question then asks for is not among the choices offered, so the answer is none.

In a row of boys, Haran is eleventh from the left and manoj is seventeenth form the right. When they exchange their places than Haran will be thirteenth from the left. Which of the following will be the new position of Manoj from the right ?
Answer: B
Correct answer: 19
After the exchange Haran stands 13th from the left, which was Manoj’s place - so Manoj was 13th from the left as well as 17th from the right, and the row holds \( 13 + 17 - 1 = 29 \) boys. Manoj now stands where Haran was, 11th from the left, which is \[ 29 - 11 + 1 = \mathbf{19} \] from the right.

Manoj and Satya are ranked seventh and eleventh respectively from the top in a class of 31 students. What will be their respective ranks from the bottom in the class ?
Answer: A
Correct answer: 25th and 21st
In a class of 31, a rank of \( r \) from the top is \( 31-r+1 \) from the bottom. Manoj at 7 becomes \( 31-7+1 = \mathbf{25} \)th and Satya at 11 becomes \( 31-11+1 = \mathbf{21} \)st.

The priest told the devotee, "The temple bell is rung at regular intervals of 45 minutes. The last bell was rung five minutes ago. The Next bell is due to be rung at 7:45am". At what time did the priest give this information to the devotee?
Answer: B
Correct answer: 7.05 am
The bells are 45 minutes apart, so the one before the 7:45 bell was rung at 7:00. That was five minutes earlier, which puts the conversation at \[ 7{:}00 + 5\text{ min} = \mathbf{7{:}05\ am} \]

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
Answer: C
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.

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 ?
Answer: B
Correct answer: P
Working the seating out from the conditions - P second to T’s right, T between R and V, S away from P, and V beside the remaining pair - the arrangement comes out uniquely, and the seat asked about is P’s.

How many 7’s are there in the following series which are not immediately followed by 3 but immediately preceded by 8?
8 9 8 7 6 2 2 6 3 2 6 9 7 3 2 8 7 2 7 7 8 7 3 7 7 9 4
Answer: C
Correct answer: 2
Two 7s have an 8 immediately before them and something other than 3 after them: 8 7 6 and 8 7 2. The 7 in 8 7 3 is ruled out by the 3 that follows. So there are 2.
