Step-by-step explanation:

980 boys are there

Answer 2

Solution :-

Given

• Number of students = 1400

• Number of girls = 420

Now we have to find out the % of boys in the school.

$\%_{boys} = \sf{\dfrac{Number\: of \: Boys}{1400}\times 100}$

Number of boys

= 1400 - Number of girls

= 1400 - 420

= 980

% boys

$\%_{boys} = \sf{\dfrac{980}{1400}\times 100}$

$\%_{boys} = \sf{\dfrac{980}{14}}$

$\%_{boys} = 70\%$
