Men |
Women |
| Before |
3 u |
1 u |
| Change |
+ 51 |
+ 37 |
| After |
3 u + 51 |
1 u + 37 |
If there are another 94 women in the end, the number of women and men will be the same.
3 u + 51 = 1 u + 37 + 94
3 u - 1 u = 131 - 51
2 u = 80
1 u = 80 ÷ 2 = 40
Number of customers in the end
= 3 u + 51 + 1 u + 37
= 4 u + 88
= 4 x 40 + 88
= 160 + 88
= 248
Answer(s): 248
