Solution
Total strength of class = 65
Total strength of girls = 30
Hence, total number of boys in a class will be
Boys = 65 – 30
= 35
The ratio of girls to boys will be as given below:
30: 35 = 30 / 35
On calculating further, we get
= 6 / 7
= 6: 7
∴ The ratio between girls and boys will be 6: 7
Total strength of class = 65
Total strength of girls = 30
Hence, total number of boys in a class will be
Boys = 65 – 30
= 35
The ratio of girls to boys will be as given below:
30: 35 = 30 / 35
On calculating further, we get
= 6 / 7
= 6: 7
∴ The ratio between girls and boys will be 6: 7
