A moment ago, there were a total of 1313 spectators at a squash match. 398 of the male spectators and 535 of the female spectators left the stadium. Now there are thrice 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
= 1313 - 398 - 535
= 380

Number of female spectators in the end = 1 u
Number of male spectators in the end = 3 u
Total number of spectators in the end = 1 u + 3 u = 4 u

4 u = 380
1 u = 380 ÷ 4 = 95

Number of female spectators
= 1 u 
= 95

Number of male spectators
= 3 u
= 3 x 95
= 285

Number of male spectators more than the female spectators
= 285 - 95
= 190

Answer(s): 190
