Men |
Women |
Before |
7 u |
2 u |
Change |
+ 65 |
+ 27 |
After |
7 u + 65 |
2 u + 27 |
If there are another 93 women in the end, the number of women and men will be the same.
7 u + 65 = 2 u + 27 + 93
7 u - 2 u = 120 - 65
5 u = 55
1 u = 55 ÷ 5 = 11
Number of customers in the end
= 7 u + 65 + 2 u + 27
= 9 u + 92
= 9 x 11 + 92
= 99 + 92
= 191
Answer(s): 191
