A moment ago, there were a total of 1955 spectators at a squash match. 317 of the male spectators and 502 of the female spectators left the stadium. Now there are thrice 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
= 1955 - 317 - 502
= 1136

Number of female spectators in the end = 1 u
Number of male spectators in the end = 3 u
Total number of spectators in the end = 1 u + 3 u = 4 u

4 u = 1136
1 u = 1136 ÷ 4 = 284

Number of female spectators
= 1 u 
= 284

Number of male spectators
= 3 u
= 3 x 284
= 852

Number of male spectators more than the female spectators
= 852 - 284
= 568

Answer(s): 568
