Men |
Women |
Before |
5 u |
2 u |
Change |
+ 58 |
+ 35 |
After |
5 u + 58 |
2 u + 35 |
If there are another 104 women in the end, the number of women and men will be the same.
5 u + 58 = 2 u + 35 + 104
5 u - 2 u = 139 - 58
3 u = 81
1 u = 81 ÷ 3 = 27
Number of customers in the end
= 5 u + 58 + 2 u + 35
= 7 u + 93
= 7 x 27 + 93
= 189 + 93
= 282
Answer(s): 282
