Question

2/5 of total number of student of a school come by car while 1/4 students come by bus to school. all the other students walk to school of which 1/3 walk on their own and the rest are escorted by their parents. If 224 students come to school walking on their own, how many students study in that school?

Answer 1

Call the total number of students $x$.

We know that $x\frac{2}{5}$ of number of students come by car while $x\frac{1}{4}$ come by bus and $\frac{1}{3}$ walk alone to school and the rest are escorted by their parents.

We also know that 224 students walk on their own. And it is represented as $\frac{1}{3}$. This might as well means that$x\frac{1}{3}=224$. We can continue that to find how much is total.

$x\frac{1}{3}=224$
$\frac{x}{3}=224$
$224*3=x$
$x=732$.

Therefore the total number of students is 732.
