A moment ago, there were a total of 1291 spectators at a badminton match. 367 of the female spectators and 448 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
= 1291 - 367 - 448
= 476

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 = 476
1 u = 476 ÷ 4 = 119

Number of male spectators
= 1 u 
= 119

Number of female spectators
= 3 u
= 3 x 119
= 357

Number of female spectators more than the male spectators
= 357 - 119
= 238

Answer(s): 238
