A moment ago, there were a total of 1598 spectators at a squash match. 280 of the male spectators and 453 of the female spectators left the stadium. Now there are four times as many male as female spectators left in the stadium. How many more male than female spectators are there in the stadium now?
Number of spectators left in the stadium
= 1598 - 280 - 453
= 865

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

5 u = 865
1 u = 865 ÷ 5 = 173

Number of female spectators
= 1 u 
= 173

Number of male spectators
= 4 u
= 4 x 173
= 692

Number of male spectators more than the female spectators
= 692 - 173
= 519

Answer(s): 519
