    B.

    25

    C.

    20

    D.

    30

    Correct option is D

    Given:

    Total pages in the chapter = 75

    Fraction of chapter Maddy has read =35 \frac{3}{5}​​

    Formula Used:

    Pages read = Fraction read× Total pages

    Remaining pages = Total pages− Pages read

    Solution:
