A Correct answer
Explanation

Let daughter's age = x. Rita = 4x. Mother = 4x / (2/3) = 6x. Total = x + 4x + 6x = 11x = 154. x = 14. Rita = 56, Mother = 84. Difference = 84 - 56 = 28.

AI explanation

Let Rita's present age be R; since it is two-thirds of her mother's age, her mother's age is 1.5R. Because Rita's age is four times her daughter's age, her daughter's age is 0.25R. The total of their present ages is R + 1.5R + 0.25R = 154, so 2.75R = 154, which means R = 56. The difference between Rita's and her mother's ages is 1.5(56) - 56 = 28 years.
