    The cost of painting the walls of a room 9 metres long and 6 metres wide at Rs. 15.50 per sq metre is Rs. 2557.50. What is the height of the room?

    A)  5.75m             

    B)  6.2m   

    C) 5.5m               

    D) 6m

    E) 6.5m

    Correct Answer: C

    Solution :

    Let the height of the room be h meters. \[\therefore \] Area of the four walls = 2h(l + b) = 2h(9 +6) = 30h Now, \[30h=\frac{2557.5}{15.5}=165\] \[\therefore h=\frac{165}{30}=5.5m\]
