A moment ago, there were a total of 1582 spectators at a squash match. 243 of the male spectators and 499 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
= 1582 - 243 - 499
= 840

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 = 840
1 u = 840 ÷ 3 = 280

Number of female spectators
= 1 u 
= 280

Number of male spectators
= 2 u
= 2 x 280
= 560

Number of male spectators more than the female spectators
= 560 - 280
= 280

Answer(s): 280
