78 of the customers were men. Within five minutes, 70 more men and 25 more women entered the supermarkets. As a result, there were 93 more men than women. How many customers were there altogether in the end?

Men |
Women |
Before |
7 u |
1 u |
Change |
+ 70 |
+ 25 |
After |
7 u + 70 |
1 u + 25 |
If there are another 93 women in the end, the number of women and men will be the same.
7 u + 70 = 1 u + 25 + 93
7 u - 1 u = 118 - 70
6 u = 48
1 u = 48 ÷ 6 = 8
Number of customers in the end
= 7 u + 70 + 1 u + 25
= 8 u + 95
= 8 x 8 + 95
= 64 + 95
= 159
Answer(s): 159
