Women |
Men |
Before |
5 u |
2 u |
Change |
+ 57 |
+ 28 |
After |
5 u + 57 |
2 u + 28 |
If there are another 95 men in the end, the number of men and women will be the same.
5 u + 57 = 2 u + 28 + 95
5 u - 2 u = 123 - 57
3 u = 66
1 u = 66 ÷ 3 = 22
Number of customers in the end
= 5 u + 57 + 2 u + 28
= 7 u + 85
= 7 x 22 + 85
= 154 + 85
= 239
Answer(s): 239
