in a college , the ratio of the number of boys to girls is 8 : 4 . if there are 200 girls , the total number of students in the college is
"explanation : let the boy are 8 x and girls are 4 x = > 4 x = 200 = > x = 50 total students = 8 x + 4 x = 12 x = 12 ( 50 ) = 600 option c"
add(200, multiply(divide(200, 4), 8))
