Herein attaching two pictures- One with the answer and question from the Padhuka Question Bank and the other being my solution. As per Padhuka, there may be two solutions- One that gives answer of 21615 and the other giving answer of 20880. (Since there is % computation, I believe slight variance js possible) But I was informed only the method giving answer as 20880 is correct. Could you please check if both methods are correct?
Both methods were correct but assumption must be mentioned clearly .
Thank you ma'am
