A moment ago, there were a total of 1617 spectators at a tennis match. 324 of the male spectators and 447 of the female spectators left the stadium. Now there are twice 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
= 1617 - 324 - 447
= 846

Number of female spectators in the end = 1 u
Number of male spectators in the end = 2 u
Total number of spectators in the end = 1 u + 2 u = 3 u

3 u = 846
1 u = 846 ÷ 3 = 282

Number of female spectators
= 1 u 
= 282

Number of male spectators
= 2 u
= 2 x 282
= 564

Number of male spectators more than the female spectators
= 564 - 282
= 282

Answer(s): 282
