Women |
Men |
Before |
5 u |
2 u |
Change |
+ 68 |
+ 33 |
After |
5 u + 68 |
2 u + 33 |
If there are another 101 men in the end, the number of men and women will be the same.
5 u + 68 = 2 u + 33 + 101
5 u - 2 u = 134 - 68
3 u = 66
1 u = 66 ÷ 3 = 22
Number of customers in the end
= 5 u + 68 + 2 u + 33
= 7 u + 101
= 7 x 22 + 101
= 154 + 101
= 255
Answer(s): 255
