A moment ago, there were a total of 1832 spectators at a tennis match. 277 of the male spectators and 491 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
= 1832 - 277 - 491
= 1064

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 = 1064
1 u = 1064 ÷ 4 = 266

Number of female spectators
= 1 u 
= 266

Number of male spectators
= 3 u
= 3 x 266
= 798

Number of male spectators more than the female spectators
= 798 - 266
= 532

Answer(s): 532
