    B 66 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the numbers be тАШxтАЩ and тАШyтАЩ respectively.

    According to the question,

    тЗТ 0.66x = 0.44y

    тЗТ x/y = 0.44 / 0.66 = 2/3

    So the numbers are in the ratio 2 : 3

    Sum of the numbers = 2 + 3 = 5 units = 330

    тЗТ 1 unit = 330 ├╖ 5 = 66

    тЗТ Difference = (3 тАУ 2) units = 1 unit = 66
