34 of the customers were women. Within five minutes, 52 more women and 25 more men entered the supermarkets. As a result, there were 91 more women than men. How many customers were there altogether in the end?

Women |
Men |
Before |
3 u |
1 u |
Change |
+ 52 |
+ 25 |
After |
3 u + 52 |
1 u + 25 |
If there are another 91 men in the end, the number of men and women will be the same.
3 u + 52 = 1 u + 25 + 91
3 u - 1 u = 116 - 52
2 u = 64
1 u = 64 ÷ 2 = 32
Number of customers in the end
= 3 u + 52 + 1 u + 25
= 4 u + 77
= 4 x 32 + 77
= 128 + 77
= 205
Answer(s): 205
