A moment ago, there were a total of 1706 spectators at a tennis match. 239 of the female spectators and 459 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
= 1706 - 239 - 459
= 1008

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 = 1008
1 u = 1008 ÷ 4 = 252

Number of male spectators
= 1 u 
= 252

Number of female spectators
= 3 u
= 3 x 252
= 756

Number of female spectators more than the male spectators
= 756 - 252
= 504

Answer(s): 504
