Men |
Women |
Before |
7 u |
1 u |
Change |
+ 63 |
+ 32 |
After |
7 u + 63 |
1 u + 32 |
If there are another 109 women in the end, the number of women and men will be the same.
7 u + 63 = 1 u + 32 + 109
7 u - 1 u = 141 - 63
6 u = 78
1 u = 78 ÷ 6 = 13
Number of customers in the end
= 7 u + 63 + 1 u + 32
= 8 u + 95
= 8 x 13 + 95
= 104 + 95
= 199
Answer(s): 199
