|
Women |
Men |
Before |
7 u |
3 u |
Change |
+ 52 |
+ 20 |
After |
7 u + 52 |
3 u + 20 |
If there are another 108 men in the end, the number of men and women will be the same.
7 u + 52 = 3 u + 20 + 108
7 u - 3 u = 128 - 52
4 u = 76
1 u = 76 ÷ 4 = 19
Number of customers in the end
= 7 u + 52 + 3 u + 20
= 10 u + 72
= 10 x 19 + 72
= 190 + 72
= 262
Answer(s): 262
