Q21: Given below is the attendance of  students of 5 different classes on  Wednesday. Study the table given  below and answer the following  question.

Which two classes have an equal  number of students absent on  Wednesday?  
(a) Class IV and Class V  
(b) Class II and Class III  
(c) Class I and Class II  
(d) Class III and Class V 

View Answer  

Ans: (c) 
Total number of students in Class I = 20  
Number of present students in  Class I = 10  
Number of absent students in Class I  = 20 –10 = 10  
Total number of students in Class II  = 25  
Number of present students in  Class II = 15  
Number of absent students in Class  II = 25 – 15 = 10  
Total number of students in Class III  = 30  
Number of present students in  Class III = 27  
Number of absent students in Class III  = 30 – 27 = 3  
Total number of students in Class  IV =35  
Number of present students in  Class IV = 20  
Number of absent students in Class  IV = 35 – 20 = 15 
Total number of students in Class V  = 40 
Number of present students in  Class V = 35  
Number of absent students in Class  V = 40 – 35 = 5  
Therefore, Class I and Class II have the same number of absentees.

Weight on pan A = 100 g + weight of apple

So, Weight of apple = 250 g – 100 g = 150 g
