There are 416 students who are enrolled in an introductory geology course. if there are seven boys to every six girls, how many
Alenkinab [10]

\text{Let the number of boys be x and number of girls be y.}\\&#10;\\&#10;\text{and there are total 416 students enrolled in the course. so we have}\\&#10;\\&#10;x+y=416 \ \ \ \ \ \ \ \ \ \ ......(i)\\&#10;\\&#10;\text{also given that there are seven boys to every six girls, that is}\\&#10;\\&#10;\frac{x}{y}=\frac{7}{6}

\Rightarrow 6x=7y\\&#10;\\&#10;\Rightarrow y=\frac{6x}{7}\\&#10;\\&#10;\text{substitute this value of y in (i), we get}\\&#10;\\&#10;x+\frac{6x}{7}=416\\&#10;\\&#10;\Rightarrow \frac{7x+6x}{7}=416\\&#10;\\&#10;\Rightarrow \frac{13x}{7}=416\\&#10;\\&#10;\Rightarrow x=\frac{416\times 7}{13}\\&#10;\\&#10;\Rightarrow x=224

Hence the number of boys in the course are: 224
