Men |
Women |
Before |
7 u |
1 u |
Change |
+ 59 |
+ 35 |
After |
7 u + 59 |
1 u + 35 |
If there are another 90 women in the end, the number of women and men will be the same.
7 u + 59 = 1 u + 35 + 90
7 u - 1 u = 125 - 59
6 u = 66
1 u = 66 ÷ 6 = 11
Number of customers in the end
= 7 u + 59 + 1 u + 35
= 8 u + 94
= 8 x 11 + 94
= 88 + 94
= 182
Answer(s): 182
