Men |
Women |
Before |
7 u |
4 u |
Change |
+ 62 |
+ 30 |
After |
7 u + 62 |
4 u + 30 |
If there are another 98 women in the end, the number of women and men will be the same.
7 u + 62 = 4 u + 30 + 98
7 u - 4 u = 128 - 62
3 u = 66
1 u = 66 ÷ 3 = 22
Number of customers in the end
= 7 u + 62 + 4 u + 30
= 11 u + 92
= 11 x 22 + 92
= 242 + 92
= 334
Answer(s): 334
