"let the number of boys and girls be 2 x and 3 x their increased number is 110 % of 2 x and 120 % of 3 x 2 x * 110 / 100 and 3 x * 120 / 100 11 x / 5 and 18 x / 5 required ratio = 11 x / 5 : 18 x / 5 = 11 : 18 answer is d"
divide(multiply(2, add(divide(10, const_100), const_1)), multiply(3, add(divide(20, const_100), const_1)))
