A moment ago, there were a total of 1907 spectators at a tennis match. 363 of the female spectators and 544 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
= 1907 - 363 - 544
= 1000

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 = 1000
1 u = 1000 ÷ 4 = 250

Number of male spectators
= 1 u 
= 250

Number of female spectators
= 3 u
= 3 x 250
= 750

Number of female spectators more than the male spectators
= 750 - 250
= 500

Answer(s): 500
