Women |
Men |
Before |
7 u |
1 u |
Change |
+ 67 |
+ 25 |
After |
7 u + 67 |
1 u + 25 |
If there are another 108 men in the end, the number of men and women will be the same.
7 u + 67 = 1 u + 25 + 108
7 u - 1 u = 133 - 67
6 u = 66
1 u = 66 ÷ 6 = 11
Number of customers in the end
= 7 u + 67 + 1 u + 25
= 8 u + 92
= 8 x 11 + 92
= 88 + 92
= 180
Answer(s): 180
