More easiest way to solve this question will be Let Income of both X and Y be 240 240/15:240/16=16:15 |

@Rahul. Why have you assumed income as 240? and why not any other number? |

From profit formula, we can write expenditure=(income*100)/(profit+100) . Now calculate ratio of expenditures of both companies. i.e. E(X)/E(Y)= {(income(x)*100)/(profit(x)+100) }/ { (income(y)*100)/(profit(y)+100)}. As, income(x) = income(y). Therefore E(X)/E(Y) = (profit(y) + 100)/(profit(x) + 100). = (60+100)/(50+100). = 160/150. E(X)/E(Y) = 16:15. |
