In a supermarkets,
57 of the customers were women. Within five minutes, 56 more women and 26 more men entered the supermarkets. As a result, there were 99 more women than men. How many customers were there altogether in the end?

Women |
Men |
Before |
5 u |
2 u |
Change |
+ 56 |
+ 26 |
After |
5 u + 56 |
2 u + 26 |
If there are another 99 men in the end, the number of men and women will be the same.
5 u + 56 = 2 u + 26 + 99
5 u - 2 u = 125 - 56
3 u = 69
1 u = 69 ÷ 3 = 23
Number of customers in the end
= 5 u + 56 + 2 u + 26
= 7 u + 82
= 7 x 23 + 82
= 161 + 82
= 243
Answer(s): 243
