in a college , the ratio of the number of boys to girls is 6 : 5 . if there are 200 girls , the total number of students in the college is
"explanation : let the boy are 6 x and girls are 5 x = > 5 x = 200 = > x = 40 total students = 6 x + 5 x = 11 x = 11 ( 40 ) = 440 option a"
add(200, multiply(divide(200, 5), 6))
