A moment ago, there were a total of 1688 spectators at a badminton match. 211 of the male spectators and 485 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
= 1688 - 211 - 485
= 992

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 = 992
1 u = 992 ÷ 4 = 248

Number of female spectators
= 1 u 
= 248

Number of male spectators
= 3 u
= 3 x 248
= 744

Number of male spectators more than the female spectators
= 744 - 248
= 496

Answer(s): 496
