(i)   Ahmed is taller than Salim.

      i.e.,  Ahmed > Salim → (i)

(ii)  Salim is not as tall as Ahmed but taller than Akbar.

     i.e.,  Ahmed > Salim > Akbar  → (ii)

(iii)  Sohan too is not as tall as Salim but taller than Akbar. 

     i.e.,  Ahmed > Salim > Sohan > Akbar

Hence, Ahmed is the tallest.

(i)  A is shorter than B but longer than E.

      i.e.,  B > A > E → (i)

(ii)  C is the longest and D is little shorter than B and little longer than A

      i.e.,  C > B > D > A  → (ii)

From (i) and (ii) we can write the order :

     C > B > D > A > E

Hence,  E is the shortest river.

8.  Sumit ranked ninth from top and thirty eighth from the bottom in a class. How many students are there in the class ?

(a) 47

(b) 48

(c) 45

(d) 46    (ANS)  

Hints & Solutions :  From formula,

Total number of students in the class = (Sumit's  rank from top) + (Sumit's rank from the bottom) - 1

= 9 + 38 - 1 = 47 - 1 = 46

9.  In a row of trees one tree is fifth from either end of the row. How many trees are there in the row ?

(a) 8

(b) 9    (ANS)  

(c) 10

(d) 11

Hints & Solutions :  One tree is fifth from either end of the row.  That means, four trees are before and four trees are after that tree.

 âˆ´    Total number of trees = 4 + 1 + 4 = 9

10.  In a queue, Amrita is 10th from the front while Mukul is 25th from rear and Mamta is just in the middle of the two. If there are 50 persons in the queue, what position does Mamta occupy from the front ?

(d) 17th

11.  If Atul finds that he is twelfth from the right in a queue of boys and fourth from the left, how many boys should be added to the queue so that there are 28 boys in the queue ?

(a) 12

(b) 13    (ANS)  

(c) 14

(d) 20

Hints & Solutions :  From formula,  total number of boys in the queue = (Atul's rank from left) + (Atul's rank from right) - 1

= 12 + 4 - 1 = 15

 âˆ´    Total number of boys that should be added

= 28 - 15 = 13.

12.  Manish ranked sixteenth from the top and twenty ninth from the bottom among those who passed an examination.  Six boys did not participate in the competition and five failed in it. How many boys were there in the class ?

(a) 40

(b) 44

(c) 50

(d) 55    (ANS)  

Hints & Solutions :  From formula, total number of passed students = (Manisha's rank from the top) + (Manisha's rank from the bottom) - 1

= 16 + 29 - 1 = 4

 âˆ´    Total number of boys in the class

= Passed students + failed students + absent students

= 44 + 6 + 5 = 55

13.  Aruna ranks twelfth in a class of forty six.  What will be her rank from the last ?

(a) 33

(b) 34

(c) 35    (ANS)  

(d) 37

Hints & Solutions :   From formula,

Aruna's  rank from the last =  (total number of girls in the class) - (Aruna's rank from the top) + 1

= 46 - 12 + 1 = 47 - 12 = 35th

14.  Ravi is 7 ranks ahead of Sumit in a class of 39. If Sumit's rank is seventeenth from the last, what is Ravi's rank from the start ?

(a) 14th

(b) 15th

(c) 16th    (ANS)  

(d) 17th

Hints & Solutions :  Ravi is 7 ranks ahead of Sumit.  That  means, 6 students are there between Ravi and Sumit.  Sumit's  rank is 17th from the last.

Total number of students  = 39

Total number of boys before Ravi = 39 - (16 + 1 + 6 + 1)

= 39 - 24 = 15

∴    Ravi's rank is 16th from the start.

15.  In a class of 60 where girls are twice that of boys, Kamal ranked seventeenth from the top.  If there are 9 girls a head of Kamal, how many boys are after him in rank ?

16.  In a row of ten boys, when Rohit was shifted by two places towards the left, he became seventh from the left end.  What was his earlier position from the right end of the row ?

(a) First

(b) Second   (ANS)  

(c) Fourth

(d) Sixth

Hints & Solutions :  By shifting towards left by two places, Rohit's rank becomes seventh from the left.  That means his earlier rank was ninth from the left.  ie,  8 boys were before him.

∴    His earlier position from the right end = (total number of boys) - (his rank from the left end) + 1

= 10 - 9 + 1 = 2 = 2nd

17.  In a queue, Vijay is fourteenth from the front and Jack is seventeenth from the end,  while Mary is in between Vijay and Jack.  If Vijay is ahead of Jack and there are 48 persons in the queue, how many persons are there between Vijay and Mary ?

∴    Total number of girls in the row

= 14 + 8 + 8 = 30
