Men |
Women |
Before |
5 u |
2 u |
Change |
+ 52 |
+ 22 |
After |
5 u + 52 |
2 u + 22 |
If there are another 105 women in the end, the number of women and men will be the same.
5 u + 52 = 2 u + 22 + 105
5 u - 2 u = 127 - 52
3 u = 75
1 u = 75 ÷ 3 = 25
Number of customers in the end
= 5 u + 52 + 2 u + 22
= 7 u + 74
= 7 x 25 + 74
= 175 + 74
= 249
Answer(s): 249
