A moment ago, there were a total of 1798 spectators at a squash match. 357 of the female spectators and 437 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
= 1798 - 357 - 437
= 1004

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 = 1004
1 u = 1004 ÷ 4 = 251

Number of male spectators
= 1 u 
= 251

Number of female spectators
= 3 u
= 3 x 251
= 753

Number of female spectators more than the male spectators
= 753 - 251
= 502

Answer(s): 502
