Q:

152, 124, 96, 69, 40

Find the odd man out?

A) 124 B) 96
C) 69 D) 40
 
Answer & Explanation Answer: C) 69

Explanation:

The given number series is 152, 124, 96, 69, 40

152

152 - 28 = 124

124 - 28 = 96

96 - 28 = 68 (not 69)

68 - 28 = 40

 

Hence, the odd man in the given number series is 69.

Answer

1. ANSWER : C 


 Explanation -  Number of students who passed half-yearly exams in the school 


= (Number of students passed in half-yearly but failed in annual exams) + (Number of students passed in both exams)
= (6 + 17 + 9 + 15) + (64 + 55 + 46 + 76)

= 288.

Also, Number of students who passed annual exams in the school

= (Number of students failed in half-yearly but passed in annual exams) + (Number of students passed in both exams)

= (14 + 12 + 8 + 13) + (64 + 55 + 46 + 76)

= 288.

Since, the number of students passed in half-yearly = the number of students passed in annual exams. Therefore, it can be inferred that both the examinations had almost the same difficulty level.

Thus Statements (a), (b) and (d) are false and Statement (c) is true. 


 


 2. ANSWER : D 


 Explanation -  Since the classification of the students on the basis of their results and sections form independent groups, so the total number of students in the class: 


 = (28 + 23 + 17 + 27 + 14 + 12 + 8 + 13 + 6 + 17 + 9 + 15 + 64 + 55 + 46 + 76)

= 430. 


 


 3. ANSWER : D 


 ExplanationPass percentages in at least one of the two examinations for different sections are:


  For Section A = 14+6+6428+14+6+64×100 = 84112×100% = 75%


 For Section B =12+17+5523+12+17+55×100  % = 78.5%


 For Section C = 8+9+4617+8+9+46×100%= 78.75%


 For Section D = 13+15+7627+13+15+76×100%= 79.39%


  Clearly ,the pass percentage is maximum for Section D 


 


  


 4. ANSWER : A


 Explanation - Total number of students passed in annual exams in a section 


= [ (No. of students failed in half-yearly but passed in annual exams) + (No. of students passed in both exams) ] in that section


 Success rate in annual exams in Section A= 14+64112 × 100% = 69.64%


 Similarly, success rate in annual exams in:


 Section B = 12+55107×100% =  62.62% 


 Section C = 8+4680×100% = 67.5% 


 Section D = 89131×100% = 67.94% 


 Clearly, the success rate in annual examination is maximum for Section A. 


 


  


 5. ANSWER : D 


 Explanation - Total number of failures in half-yearly exams in a section


  = [ (Number of students failed in both exams) + (Number of students failed in half-yearly but passed in Annual exams) ] in that section


 Failure rate in half-yearly exams in Section A %= 37.5 %


 Similarly, failure rate in half-yearly exams in:


  Section B = 32.71%


  Section C = 31.25%


  Section D = 30.53%


  Clearly, the failure rate is minimum for Section D.


 = (Number of students passed in half-yearly but failed in annual exams) + (Number of students passed in both exams)


 = (6 + 17 + 9 + 15) + (64 + 55 + 46 + 76)


 = 288.


 


 Also, Number of students who passed annual exams in the school


 = (Number of students failed in half-yearly but passed in annual exams) + (Number of students passed in both exams)


 = (14 + 12 + 8 + 13) + (64 + 55 + 46 + 76)


 = 288.


 


Since, the number of students passed in half-yearly = the number of students passed in annual exams. Therefore, it can be inferred that both the examinations had almost the same difficulty level.


Thus Statements (a), (b) and (d) are false and Statement (c) is true.

Q:

Pick the odd man out of the folowing number sequence?

123 112 133 112 143

A) 143 B) 122
C) 133 D) 112
 
Answer & Explanation Answer: B) 122

Explanation:

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

 

Hence, the odd man in the given number sequence is 122 instead of 102.
