Men |
Women |
Before |
5 u |
1 u |
Change |
+ 58 |
+ 20 |
After |
5 u + 58 |
1 u + 20 |
If there are another 102 women in the end, the number of women and men will be the same.
5 u + 58 = 1 u + 20 + 102
5 u - 1 u = 122 - 58
4 u = 64
1 u = 64 ÷ 4 = 16
Number of customers in the end
= 5 u + 58 + 1 u + 20
= 6 u + 78
= 6 x 16 + 78
= 96 + 78
= 174
Answer(s): 174
