Men |
Women |
Before |
5 u |
2 u |
Change |
+ 52 |
+ 35 |
After |
5 u + 52 |
2 u + 35 |
If there are another 104 women in the end, the number of women and men will be the same.
5 u + 52 = 2 u + 35 + 104
5 u - 2 u = 139 - 52
3 u = 87
1 u = 87 ÷ 3 = 29
Number of customers in the end
= 5 u + 52 + 2 u + 35
= 7 u + 87
= 7 x 29 + 87
= 203 + 87
= 290
Answer(s): 290
