Count each 7 which is not immediately preceded by 5 but is immediately followed by either 2 or 3. How many such 7’s are there?
5 7 2 6 5 7 3 8 3 7 3 2 5 7 2 7 3 4 8 2 6 7 8
Answer: A
Correct answer: 2
Two 7s qualify: the one in 3 7 3, which is preceded by 3 and followed by 3, and the one in 2 7 3. The 7s in 5 7 2 and 5 7 3 are ruled out by the 5 before them, and the last 7 is followed by 8. So there are 2.

If it is possible to make a number which is the square of a two-digit odd number using the second, the fourth and the sixth digits of the number 93217648 and using each only once, which of the following is that two-digit odd number?
Answer: B
Correct answer: 19
The second, fourth and sixth digits of 93217648 are 3, 1 and 6. Arranged as 361 they give \( 19^2 \), and 19 is a two-digit odd number - so the number whose square can be formed is 19.

The position of the first and the second digits in the numbers 94316875 are interchanged. Similarly, the positions of the third and fourth digits are interchanged and so on. Which of the following will be the third to the left of the seventh digit from the left end after the rearrangement?
Answer: D
Correct answer: None of these
Interchanging the digits in pairs turns 94316875 into 49138657. The seventh digit from the left is then 5, and the third place to its left is the fourth digit, 3 - which is not among the choices offered, so the answer is none of these.

382 473 568 728 847 629
If 382 is written as 238, 473 as 347 and so on, then which of the following two numbers will have least difference between them?
Answer: D
The given numbers are :
382 473 568 728 847 629
When changes are made as given in the question, numbers become as follows :
238 347 856 872 784 962
Again now, find out the difference between the numbers given in options as given below:
(1) 473 - 382 => 347 - 238 = 109
(2) 629 - 728 => 962 - 872 = 90
(3) 629 - 847 => 962 - 784 = 178
(4) 728 - 847 => 872 - 784 = 88

How many such 5s are there in the following number sequence each of which is immediately preceded by 3 or 4 but not immediately followed by 8 or 9?
3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0
Answer: D
Correct answer: Five
Five 5s have a 3 or a 4 immediately before them and something other than 8 or 9 after them - the 5s at the sixth, twelfth, sixteenth, twenty-first and twenty-fourth places. The rest are ruled out either by what precedes them or by an 8 or 9 following. So the answer is five.

If Atul finds that he is twelfth from the right in a line of boys and forth from the left, how many boys should be added to the line such that there are 28 boys in the line ?
Answer: B
Correct answer: 13
Atul is 4th from the left and 12th from the right, so the line already holds \( 4 + 12 - 1 = 15 \) boys. To bring it to 28, \[ 28 - 15 = \mathbf{13} \] more must be added.

In a queue, Amrita is 10th from the front while Mukul is 25th from behind and Mamta is just in the middle of the two. If there be 50 persons in the queue. What position does Mamta occupy from the front ?
Answer: C
Correct answer: 18th
Mukul is 25th from behind in a queue of 50, so he is \( 50-25+1 = 26 \)th from the front. Mamta stands midway between the 10th and the 26th place: \[ \frac{10+26}{2} = \mathbf{18} \text{th} \]
