    C 7 Correct Answer Incorrect Answer
    D 8 Correct Answer Incorrect Answer

    Solution

    Flower pots  made by the person  in one hour = 48 Flower pots  made by him working 3 hours daily in one day = 48 × 3 = 144 Flower pots  made by him in 4 days = 144 × 4 = 576 Remaining flower pots  = 660 – 576 = 84 Now these 84 flower pots  will be made by his brother, in 4 days working 3 hours daily. Flower pots made by his brother in an hour = 84/(4×3) = 84/12 = 7
