x starts a business with rs . 45000 . y joins in the business after 3 months with rs . 30000 . what will be the ratio in which they should share the profit at the end of the year ?
"explanation : ratio in which they should share the profit = ratio of the investments multiplied by the time period = 45000 × 12 : 30000 × 9 = 45 × 12 : 30 × 9 = 3 × 12 : 2 × 9 = 2 : 1 answer : option b"
divide(multiply(45000, const_12), multiply(30000, add(const_4, const_3)))
