5 u |
1 u |
Change |
+ 64 |
+ 31 |
After |
5 u + 64 |
1 u + 31 |
If there are another 109 men in the end, the number of men and women will be the same.
5 u + 64 = 1 u + 31 + 109
5 u - 1 u = 140 - 64
4 u = 76
1 u = 76 ÷ 4 = 19
Number of customers in the end
= 5 u + 64 + 1 u + 31
= 6 u + 95
= 6 x 19 + 95
= 114 + 95
= 209
Answer(s): 209
