7 u |
2 u |
Change |
+ 65 |
+ 22 |
After |
7 u + 65 |
2 u + 22 |
If there are another 93 women in the end, the number of women and men will be the same.
7 u + 65 = 2 u + 22 + 93
7 u - 2 u = 115 - 65
5 u = 50
1 u = 50 ÷ 5 = 10
Number of customers in the end
= 7 u + 65 + 2 u + 22
= 9 u + 87
= 9 x 10 + 87
= 90 + 87
= 177
Answer(s): 177
