Men |
Women |
Before |
7 u |
3 u |
Change |
+ 62 |
+ 37 |
After |
7 u + 62 |
3 u + 37 |
If there are another 97 women in the end, the number of women and men will be the same.
7 u + 62 = 3 u + 37 + 97
7 u - 3 u = 134 - 62
4 u = 72
1 u = 72 ÷ 4 = 18
Number of customers in the end
= 7 u + 62 + 3 u + 37
= 10 u + 99
= 10 x 18 + 99
= 180 + 99
= 279
Answer(s): 279
