The Bar graph given below presents the number of males and females working in five different companies.

What is the ratio of the total number of males working in the Companies C2 and C3 to the total number of females working in C1 and C5?

From the given Bar graph (blue bar depicts number of males working in the respective company and orange bar depicts the number of females working in the respective company)

we observe that

no of males working in company C2 = 89

no of males working in company C3= 92

total no of males working companies in C2 and C3 = 89 + 92 = 181

no of females working in company C5= 36

total number of females working in C1 and C5 = 81 + 36 = 117

total number of males working in C2 and C3 : total number of females working in C1 and C5 = 181:117
