Number of male and female members in different organizations A, B, C, D and E are given in the bar graph.
What is the ratio of average number of females in all the five organisations to the average number of males in all the five organisations?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 46 : 49
Total number of males in all five organizations = (250 + 225 + 325 + 275 + 150)
⇒ 1225
Average number of males in all five organizations = 1225/5 = 245
The total number of females in all five organizations = (300 + 275 + 250 + 200 + 125)
⇒ 1150
The average number of females in all five organizations = 1150/5 = 230
Required ratio = 230 : 245
⇒ 46 : 49
