According to given bar graph , we have
Number of persons in the age group of 20 – 25 = 250
Number of persons in the age group of 30 – 35 = 75
Required ratio = Number of persons in the age group of 20 – 25 : Number of persons in the age group of 30 – 35Correct Option: C
According to given bar graph , we have
Number of persons in the age group of 20 – 25 = 250
Number of persons in the age group of 30 – 35 = 75
Required ratio = Number of persons in the age group of 20 – 25 : Number of persons in the age group of 30 – 35
Required ratio = 250 : 75 = 10 : 3
