A moment ago, there were a total of 1610 spectators at a squash match. 235 of the female spectators and 445 of the male spectators left the stadium. Now there are twice as many female as male spectators left in the stadium. How many more female than male spectators are there in the stadium now?
Number of spectators left in the stadium
= 1610 - 235 - 445
= 930

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

3 u = 930
1 u = 930 ÷ 3 = 310

Number of male spectators
= 1 u 
= 310

Number of female spectators
= 2 u
= 2 x 310
= 620

Number of female spectators more than the male spectators
= 620 - 310
= 310

Answer(s): 310
