At a supermarket, there were
14 as many persimmons as guavas. After 4 persimmons and 25 guavas were sold, the number of persimmons became the same as the number of guavas. How many fruits were at the supermarket in the end?
|
Persimmons |
Guavas |
Before |
1 u |
4 u |
Change |
- 4 |
- 25 |
After |
1 u - 4 |
4 u - 25 |
Number of persimmons and guavas in the end is the same.
4 u - 25 = 1 u - 4
4 u - 1 u = 25 - 4
3 u = 21
1 u = 21 ÷ 3 = 7
Number of fruits in the end
= 1 u - 4 + 4 u - 25
= 5 u - 29
= 5 x 7 - 29
= 35 - 29
= 6
Answer(s): 6
