    Explanation:

    Let he mixes the oils in the ratio = x : y

    Then, the cost price of the oils = 60x + 65y

    Given selling price = Rs. 68.20

    =Selling price = 68.20(x+y)

    Given profit = 10% = SP - CP

    =10/100 (60x + 65y) = 68.20(x+y)-(60x + 65y)

    = 6x + 6.5y = 8.20x + 3.20y

    =2.2x = 3.3y

    =x : y = 3 : 2

    Hence, option 2 is the correct answer.
