  1. Correct Answer – Option 1 : 360

    Given:

    Deepak’s total marks = 256

    Chintu’s marks = 25% more than Deepak

    Bittu’s marks = 10% less than Chintu

    Asha’s marks = 25% more than Bittu

    Calculations:

    Let Deepak’s marks be 100

    Chintu got 25% marks more than Deepak.

    So, Marks obtained by Chintu = 125

    Bittu got 10% marks less than Chintu.

    So, Marks obtained by Bittu = 125 × (90/100)

    Asha got 25% more marks than Bittu.

    So, Marks obtained by Asha = 125 × (90/100) × (125/100) = 1125/8

    Now, Deepak’s marks = 256

    Marks obtained by Asha = (256/100) × (1125/8) = 360

    ∴ Asha got 360 marks out of 500.
