Answer:

Let the no. of boys = 5x

and no. of girls = 2x

Total no. of students = 700

acc. to question :-

5x+2x = 700

7x = 700

 \tt \: x =  \frac{700}{7}  \\  \tt \: x = 100

No. of boys = 5x

= 5×100 = 500

 \tt \:  \: percentage \: of \: boys \:  = ( \frac{no \: of \: boys}{total \: students }  \times 100)\% \\  \tt \:  = ( \frac{500}{700}  \times 100)\% \\ 71.4\%

hope it helps you dear ...
