Question

The School Education and Reading Culture Conference was organized in the Colors Hall. The maximum number of seats in a row was two-fifths (1/4). If the number of seats in each row was doubled, there would have been twice as many queues. How many delegates were present for the council if no single seat was vacant in the House?

Answer 1
