Women |
Men |
Before |
7 u |
4 u |
Change |
+ 68 |
+ 31 |
After |
7 u + 68 |
4 u + 31 |
If there are another 94 men in the end, the number of men and women will be the same.
7 u + 68 = 4 u + 31 + 94
7 u - 4 u = 125 - 68
3 u = 57
1 u = 57 ÷ 3 = 19
Number of customers in the end
= 7 u + 68 + 4 u + 31
= 11 u + 99
= 11 x 19 + 99
= 209 + 99
= 308
Answer(s): 308
