    In 2008, the number of students studying Arts and commerce together
    = (12 + 22)/100 x 35000
    In 2009, the number of students studying Arts and Commerce together
    = (11 + 24)/100 x 40000

    Correct Option: D

    In 2008, the number of students studying Arts and commerce together
    = (12 + 22)/100 x 35000 = 34 x 350 = 11900
    In 2009, the number of students studying Arts and Commerce together
    = (11 + 24)/100 x 40000 = 35 x 400 = 14000
    Hence, required percentage = 11900/14000 x 100 = 85%

Direction: Study the following pie-chart and answer given below:

  1. If the total production of cars during a certain period was 42000, how many more blue cars were sold in comparison to golden cars.








  1. View Hint View Answer Discuss in Forum

    Required difference = ( blue car % - golden car % )x420000/100

    Correct Option: A

    Required difference = ( blue car % - golden car % )x420000/100
    Required difference = (12 -10)/100 x 420000 = 2/100 x 420000 = 8400

  1. Which car is 40% more popular than black cars?








  1. View Hint View Answer Discuss in Forum

    Let us assume the car which is 40% more popular than black is a and total number of car is P.

    Correct Option: D

    Let us assume the car which is 40% more popular than black is a and total number of car is P.
    According to question,
    (P x a/100 ) - (P x 5/100) = P x 5/100 x 40/100
    P(a - 5)x1/100 = P x 5/100 x 40/100
    (a - 5) = 5 x 40/100
    (a - 5) = 200/100 = 2
    a - 5 = 2
    a = 2 + 5 = 7
    40% more popular than Black cars = 7% popular Silver cars.
