A moment ago, there were a total of 1286 spectators at a squash match. 287 of the female spectators and 455 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
= 1286 - 287 - 455
= 544

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 = 544
1 u = 544 ÷ 4 = 136

Number of male spectators
= 1 u 
= 136

Number of female spectators
= 3 u
= 3 x 136
= 408

Number of female spectators more than the male spectators
= 408 - 136
= 272

Answer(s): 272
