At a mart, the ratio of apricots to peaches was 4 : 9. After Xandra bought two-fifths of the peaches, there was a total of 141 apricots and peaches left at the mart. How many fruits were there at first?

Apricots |
Peaches |
Total |
Comparing apricots and peaches at first |
4x5 = 20 u |
9x5 = 45 u |
65 u |
Before |
|
5x9 = 45 u |
|
Change |
|
- 2x9 = - 18 u |
|
After |
20 u |
3x9 = 27 u |
141 |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 9 and 5 is 45.
Total number of fruits left
= 20 u + 27 u
= 47 u
47 u = 141
1 u = 141 ÷ 47 = 3
Number of fruits at first
= 20 u + 45 u
= 65 u
= 65 x 3
= 195
Answer(s): 195
