Women |
Men |
Before |
7 u |
1 u |
Change |
+ 67 |
+ 38 |
After |
7 u + 67 |
1 u + 38 |
If there are another 107 men in the end, the number of men and women will be the same.
7 u + 67 = 1 u + 38 + 107
7 u - 1 u = 145 - 67
6 u = 78
1 u = 78 ÷ 6 = 13
Number of customers in the end
= 7 u + 67 + 1 u + 38
= 8 u + 105
= 8 x 13 + 105
= 104 + 105
= 209
Answer(s): 209
