A moment ago, there were a total of 1910 spectators at a table tennis match. 207 of the female spectators and 478 of the male spectators left the stadium. Now there are four times 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
= 1910 - 207 - 478
= 1225

Number of male spectators in the end = 1 u
Number of female spectators in the end = 4 u
Total number of spectators in the end = 1 u + 4 u = 5 u

5 u = 1225
1 u = 1225 ÷ 5 = 245

Number of male spectators
= 1 u 
= 245

Number of female spectators
= 4 u
= 4 x 245
= 980

Number of female spectators more than the male spectators
= 980 - 245
= 735

Answer(s): 735
