Men |
Women |
Before |
5 u |
2 u |
Change |
+ 54 |
+ 34 |
After |
5 u + 54 |
2 u + 34 |
If there are another 107 women in the end, the number of women and men will be the same.
5 u + 54 = 2 u + 34 + 107
5 u - 2 u = 141 - 54
3 u = 87
1 u = 87 ÷ 3 = 29
Number of customers in the end
= 5 u + 54 + 2 u + 34
= 7 u + 88
= 7 x 29 + 88
= 203 + 88
= 291
Answer(s): 291
