    B 670 Correct Answer Incorrect Answer
    C 600 Correct Answer Incorrect Answer
    D 640 Correct Answer Incorrect Answer

    Solution

    Total number of families in the colony = 20 + 30 = 50 Number of blankets received by APL families = 20 x 0.30 x 50 = 300 Number of blankets received by BPL families = 30 x 0.60 x 50 = 900 Required difference = 900 - 300 = 600
