In a supermarkets,
811 of the customers were men. Within five minutes, 70 more men and 36 more women entered the supermarkets. As a result, there were 104 more men than women. How many customers were there altogether in the end?

Men |
Women |
Before |
8 u |
3 u |
Change |
+ 70 |
+ 36 |
After |
8 u + 70 |
3 u + 36 |
If there are another 104 women in the end, the number of women and men will be the same.
8 u + 70 = 3 u + 36 + 104
8 u - 3 u = 140 - 70
5 u = 70
1 u = 70 ÷ 5 = 14
Number of customers in the end
= 8 u + 70 + 3 u + 36
= 11 u + 106
= 11 x 14 + 106
= 154 + 106
= 260
Answer(s): 260
