Men |
Women |
Before |
7 u |
4 u |
Change |
+ 61 |
+ 37 |
After |
7 u + 61 |
4 u + 37 |
If there are another 99 women in the end, the number of women and men will be the same.
7 u + 61 = 4 u + 37 + 99
7 u - 4 u = 136 - 61
3 u = 75
1 u = 75 ÷ 3 = 25
Number of customers in the end
= 7 u + 61 + 4 u + 37
= 11 u + 98
= 11 x 25 + 98
= 275 + 98
= 373
Answer(s): 373
