A moment ago, there were a total of 1594 spectators at a badminton match. 355 of the male spectators and 549 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
= 1594 - 355 - 549
= 690

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 = 690
1 u = 690 ÷ 3 = 230

Number of female spectators
= 1 u 
= 230

Number of male spectators
= 2 u
= 2 x 230
= 460

Number of male spectators more than the female spectators
= 460 - 230
= 230

Answer(s): 230
