A moment ago, there were a total of 1697 spectators at a tennis match. 400 of the female spectators and 541 of the male spectators left the stadium. Now there are twice 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
= 1697 - 400 - 541
= 756

Number of male spectators in the end = 1 u
Number of female spectators in the end = 2 u
Total number of spectators in the end = 1 u + 2 u = 3 u

3 u = 756
1 u = 756 ÷ 3 = 252

Number of male spectators
= 1 u 
= 252

Number of female spectators
= 2 u
= 2 x 252
= 504

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

Answer(s): 252
