A moment ago, there were a total of 1889 spectators at a badminton match. 337 of the female spectators and 508 of the male spectators left the stadium. Now there are thrice as many female as male spectators left in the stadium. How many more female than male spectators are there in the stadium now?
Number of spectators left in the stadium
= 1889 - 337 - 508
= 1044

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

4 u = 1044
1 u = 1044 ÷ 4 = 261

Number of male spectators
= 1 u 
= 261

Number of female spectators
= 3 u
= 3 x 261
= 783

Number of female spectators more than the male spectators
= 783 - 261
= 522

Answer(s): 522
