The ratio of guavas to persimmons is 3 : 5. If 8 persimmons are added, the ratio of guavas to persimmons will be 3 : 7. How many less guavas than persimmons are there in the end?
| |
Guavas |
Persimmons |
| Before |
3 u |
5 u |
| Change |
|
+ 8 |
| After |
3 u |
7 u |
The number of guavas at first and in the end remains unchanged.
Number of persimmons added
= 7 u - 5 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Number of less guavas than persimmons in the end
= 7 u - 3 u
= 4 u
= 4 x 4
= 16
Answer(s): 16
