in a college , the ratio of the number of boys to girls is 8 : 5 . if there are 300 girls , the total number of students in the college is
"explanation : let the boy are 8 x and girls are 5 x = > 5 x = 300 = > x = 60 total students = 8 x + 5 x = 13 x = 13 ( 60 ) = 780 option d"
add(300, multiply(divide(300, 5), 8))
