For providing a rented flat, a broker takes a brokerage that is directly proportional to the monthly rent of the flat. He showed two flats to a family, such that the monthly rent of the first flat was Rs. 35000. If the ratio of the brokerage of the two flats is 7 ∶ 4, what is the difference between the monthly rents of the two flats? Correct Answer Rs. 15000

Let the monthly rent of the second flat be Rs. ‘x’

Given, brokerage of a flat is directly proportional to the monthly rent of flat

⇒ Brokerage ∝ Monthly rent of flat

⇒ Brokerage = c × Monthly rent of flat, where c is a constant

If we consider the ratio of the brokerage of two flats, then,

⇒ Ratio of brokerage = Ratio of monthly rents

⇒ 7 ∶ 4 = 35000 ∶ x

⇒ x = 4/7 × 35000 = Rs. 20000

∴ Difference between the monthly rents = 35000 – 20000 = Rs. 15000
