A moment ago, there were a total of 1939 spectators at a badminton match. 324 of the male spectators and 439 of the female spectators left the stadium. Now there are thrice 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
= 1939 - 324 - 439
= 1176

Number of female spectators in the end = 1 u
Number of male spectators in the end = 3 u
Total number of spectators in the end = 1 u + 3 u = 4 u

4 u = 1176
1 u = 1176 ÷ 4 = 294

Number of female spectators
= 1 u 
= 294

Number of male spectators
= 3 u
= 3 x 294
= 882

Number of male spectators more than the female spectators
= 882 - 294
= 588

Answer(s): 588
