Question

the total number of students in the school are 1250.40% of the students are girls .find the number of boys

Answer 1

Total no. of students  = 1250

% of boys = 100-40 = 60%

therfore,

no. of boys = 60/100 * 1250

                   =  3*1250 / 5

                   =  3750/5

                   =  750

Answer 2

HEY MATE HERE IS UR ANSWER


GIVEN THAT

NUMBER OF TOTAL STUDENTS IN SCHOOL IS = 1250 STUDENTS

NOW ITS ALSO GIVEN THAT IN THIS 40% ARE GIRLS

SO THE PERCENTAGE OF BOYS IN SCHOOL = 100% - GIRLS PERCENTAGE

WHICH IS

100% - 40 % = 60 %

SO THE PERCENTAGE OF BOYS IS 60%

THEREFORE NUMBER OF BOYS = 60% OF 1250

WHICH IS


$\frac{60}{100 } \times 1250 = 750 \: boys$

SO THERE ARE 750 BOYS IN THE SCHOOL.
