A. 25 %

B. 20%

C. 3 %

D. None of the above

Answer : B. 20%


Explanation:

    It Can be done using a simple formula for percentage :
    Decrease in consumption = [% Price increase / (100 + % Price Increase) ] × 100
    So , If price of onion rises by 25% =>
    Decrease in consumption = [ 25 / (100 + 25) ] × 100
    = [ 25 / 125 ] × 100 = 20
