A moment ago, there were a total of 1577 spectators at a squash match. 212 of the male spectators and 528 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
= 1577 - 212 - 528
= 837

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 = 837
1 u = 837 ÷ 3 = 279

Number of female spectators
= 1 u 
= 279

Number of male spectators
= 2 u
= 2 x 279
= 558

Number of male spectators more than the female spectators
= 558 - 279
= 279

Answer(s): 279
