Women |
Men |
Before |
3 u |
1 u |
Change |
+ 63 |
+ 30 |
After |
3 u + 63 |
1 u + 30 |
If there are another 105 men in the end, the number of men and women will be the same.
3 u + 63 = 1 u + 30 + 105
3 u - 1 u = 135 - 63
2 u = 72
1 u = 72 ÷ 2 = 36
Number of customers in the end
= 3 u + 63 + 1 u + 30
= 4 u + 93
= 4 x 36 + 93
= 144 + 93
= 237
Answer(s): 237
