The table below indicates the percentage of students and the ratio of boys and girls in the various streams of a college. (Total students = 2600)

In which stream, is the difference in the percentage of boys and girls minimum?

Percentage of difference of girls and boys in CE = $$\frac{\left(104\times\ 100\right)}{312}=33.33\%$$

Percentage of difference of girls and boys in CS = $$\frac{\left(52\times\ 100\right)}{208}=25\%$$

Percentage of difference of girls and boys in CS = $$\frac{\left(78\times\ 100\right)}{234}=33.33\%$$

Percentage of difference of girls and boys in CS = $$\frac{\left(52\times\ 100\right)}{312}=16.66\%$$

Percentage of difference of girls and boys in CS =$$\frac{\left(26\times\ 100\right)}{234}=11.11\%$$

So difference of boys and girls in EC is minimum.
