  1. View Hint View Answer Discuss in Forum

    Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then
    their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x
    Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10
    Hence, the required ratio = 7x : 91x/10 = 10 : 13

    Correct Option: B

    Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then
    their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x
    Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10
    Hence, the required ratio = 7x : 91x/10 = 10 : 13

  1. What is the average number of buildings demolished across the cities?








  1. View Hint View Answer Discuss in Forum

    Average number of building = number of building across the cities (P + Q + R + S + T )/5

    Correct Option: B

    Average number of building = number of building across the cities (P + Q + R + S + T )/5
    Average number of building = 50 + 175 + 150 + 75 + 175/5 = 625/5 = 125

  1. The total number of buildings constructed across the cities is approximately what per cent of the total number of buildings redeveloped across the cities?








  1. View Hint View Answer Discuss in Forum

    Total number of buildings constructed across the cities = 200 + 100 + 225 + 300
    Total number of buildings redeveloped across the cities = 300 + 275 + 250

    Correct Option: C

    Total number of buildings constructed across the cities = 200 + 100 + 225 + 300 = 1100
    Total number of buildings redeveloped across the cities = 300 + 275 + 250 = 1400
    Required percentage = 1100 x 100 /1400 = 78.57% approx. 79%

  1. What is the difference between the total constructions (constructed, demolished and redeveloped) in city Q and city T?








  1. View Hint View Answer Discuss in Forum

    Total constructions in City Q = constructed building + demolished building + redeveloped building
    Total constructions in City T = constructed building + demolished building + redeveloped building

    Correct Option: B

    Total constructions in City Q = constructed building + demolished building + redeveloped building
    Total constructions in City Q = 100 + 175 + 275 = 550
    Total constructions in City T = constructed building + demolished building + redeveloped building
    Total constructions in City T = 175 + 250 + 300 = 725
    Their difference = 725 - 550 = 175

  1. What is the respective ratio of the number of building demolished in city T to the number of buildings redeveloped in city P?








  1. View Hint View Answer Discuss in Forum

    Required ratio = number of building demolished in City T / number of buildings redeveloped in city P

    Correct Option: D

    Required ratio = number of building demolished in City T / number of buildings redeveloped in city P
    Required ratio = 175 : 300 = 7 : 12
