34 of the customers were women. Within five minutes, 58 more women and 21 more men entered the supermarkets. As a result, there were 107 more women than men. How many customers were there altogether in the end?

Women |
Men |
Before |
3 u |
1 u |
Change |
+ 58 |
+ 21 |
After |
3 u + 58 |
1 u + 21 |
If there are another 107 men in the end, the number of men and women will be the same.
3 u + 58 = 1 u + 21 + 107
3 u - 1 u = 128 - 58
2 u = 70
1 u = 70 ÷ 2 = 35
Number of customers in the end
= 3 u + 58 + 1 u + 21
= 4 u + 79
= 4 x 35 + 79
= 140 + 79
= 219
Answer(s): 219
