1 u |
Change |
+ 65 |
+ 33 |
After |
8 u + 65 |
1 u + 33 |
If there are another 109 men in the end, the number of men and women will be the same.
8 u + 65 = 1 u + 33 + 109
8 u - 1 u = 142 - 65
7 u = 77
1 u = 77 ÷ 7 = 11
Number of customers in the end
= 8 u + 65 + 1 u + 33
= 9 u + 98
= 9 x 11 + 98
= 99 + 98
= 197
Answer(s): 197
