Find the total time taken by all three persons to complete work P
Answer (Detailed Solution Below)
Bar Graph Question 1 Detailed Solution
Formula used:
Efficiency = Total work / Time
Calculation:
Total work P is = (LCM of 10, 12, 15) = 60
Time taken by Ram to complete Work P = 10 hours
One day efficiency of Ram to complete Work P = 60 / 10 = 6
Time taken by Rohan to complete Work P = 12 hours
One day efficiency of Rohan to complete Work P = 60 / 12 = 5
Time taken by Raj to complete Work P = 15 hours
One day efficiency of Raj to complete Work P = 60 / 15 = 4
∴ Total time taken by all three persons to complete work P = 60 / (6 + 5 + 4)
= 60 / 15 = 4 hoursBar Graph Question 2:

Answer (Detailed Solution Below)
Bar Graph Question 14 Detailed Solution
Download Solution PDFGiven:-
Athletic club of 232 members and their height's frequency.
Concept used:-
Frequency Polygon:- A frequency polygon is a graph constructed by using lines to join the midpoints of each interval or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.
Formula Used:
Class size = Upper limit - Lower limit
Calculation:
From histogram -
Class size = Upper limit - Lower limit
Class size = 125 - 120 = 5
∴ Mid point of a class = 5/2 = 2.5
So, Starting point of Line graph -
X - co-ordinate = 120 - 2.5 = 117.5
Y - co-ordinate = frequency of point = 0
∴ Starting point = (117.5,0)
End point of Line graph -
X - co-ordinate = 170 + 2.5 = 172.5
Y - co-ordinate = frequency of point = 0
∴ End point = (172.5,0)
∴ Required points are (117.5,0) and (172.5,0).

Answer (Detailed Solution Below)
Bar Graph Question 15 Detailed Solution
Download Solution PDFGiven:
B(1995 + 1998) = 1620 + 1600
A(1996 + 1997) = 1590 + 1750
Solution:
The total number of coolers sold by shopkeeper B in 1995 and 1998 = 1620 + 1600 = 3220
The total number of coolers sold by shopkeeper A in 1996 and 1997 = 1590 + 1750 = 3340
difference = 3220 - 3340 = -120
⇒ less
Required percentage = 120/3340 x 100 = 3.5% ~ 4% less
Hence, the correct option is 2.
