    Answer: (4) Decrease the price by 10%
    Explanation:-
    Let  be the price of an portion = Rs.100
    Raise 20%
    Then,
    Price = 100 + 100 x20/100 = 100 + 20
    = 120
    He gave 20% discount
    Then, Price = 120 x 25/100 = 30
    thus, price of portion = 120 – 30 = 90
    Decrease the price = 100 – 90 = 10%
    Hence, the answer is (4) Decrease the price by 10%.
