A moment ago, there were a total of 1888 spectators at a badminton match. 202 of the male spectators and 531 of the female spectators left the stadium. Now there are four times 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
= 1888 - 202 - 531
= 1155

Number of female spectators in the end = 1 u
Number of male spectators in the end = 4 u
Total number of spectators in the end = 1 u + 4 u = 5 u

5 u = 1155
1 u = 1155 ÷ 5 = 231

Number of female spectators
= 1 u 
= 231

Number of male spectators
= 4 u
= 4 x 231
= 924

Number of male spectators more than the female spectators
= 924 - 231
= 693

Answer(s): 693
