A moment ago, there were a total of 1907 spectators at a table tennis match. 335 of the female spectators and 498 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
= 1907 - 335 - 498
= 1074

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 = 1074
1 u = 1074 ÷ 3 = 358

Number of male spectators
= 1 u 
= 358

Number of female spectators
= 2 u
= 2 x 358
= 716

Number of female spectators more than the male spectators
= 716 - 358
= 358

Answer(s): 358
