Men |
Women |
Before |
5 u |
3 u |
Change |
+ 69 |
+ 40 |
After |
5 u + 69 |
3 u + 40 |
If there are another 91 women in the end, the number of women and men will be the same.
5 u + 69 = 3 u + 40 + 91
5 u - 3 u = 131 - 69
2 u = 62
1 u = 62 ÷ 2 = 31
Number of customers in the end
= 5 u + 69 + 3 u + 40
= 8 u + 109
= 8 x 31 + 109
= 248 + 109
= 357
Answer(s): 357
