Women |
Men |
Before |
7 u |
2 u |
Change |
+ 56 |
+ 39 |
After |
7 u + 56 |
2 u + 39 |
If there are another 102 men in the end, the number of men and women will be the same.
7 u + 56 = 2 u + 39 + 102
7 u - 2 u = 141 - 56
5 u = 85
1 u = 85 ÷ 5 = 17
Number of customers in the end
= 7 u + 56 + 2 u + 39
= 9 u + 95
= 9 x 17 + 95
= 153 + 95
= 248
Answer(s): 248
