8 u |
1 u |
Change |
+ 55 |
+ 40 |
After |
8 u + 55 |
1 u + 40 |
If there are another 99 men in the end, the number of men and women will be the same.
8 u + 55 = 1 u + 40 + 99
8 u - 1 u = 139 - 55
7 u = 84
1 u = 84 ÷ 7 = 12
Number of customers in the end
= 8 u + 55 + 1 u + 40
= 9 u + 95
= 9 x 12 + 95
= 108 + 95
= 203
Answer(s): 203
