A moment ago, there were a total of 1817 spectators at a tennis match. 224 of the male spectators and 474 of the female spectators left the stadium. Now there are twice as many male as female spectators left in the stadium. How many more male than female spectators are there in the stadium now?
Number of spectators left in the stadium
= 1817 - 224 - 474
= 1119

Number of female spectators in the end = 1 u
Number of male spectators in the end = 2 u
Total number of spectators in the end = 1 u + 2 u = 3 u

3 u = 1119
1 u = 1119 ÷ 3 = 373

Number of female spectators
= 1 u 
= 373

Number of male spectators
= 2 u
= 2 x 373
= 746

Number of male spectators more than the female spectators
= 746 - 373
= 373

Answer(s): 373
