| Change |
- 1 u |
- 1 p |
- 30 |
| After |
5 u |
1 p |
94 |
Total number of passion fruits and oranges sold
= 124 - 94
= 30
5 u + 1 p = 94
1 p = 94 - 5 u --- (1)
1 u + 1 p = 30
1 p = 30 - 1 u --- (2)
(2) = (1)
30 - 1 u = 94 - 5 u
5 u - 1 u = 94 - 30
4 u = 64
1 u = 64 ÷ 4 = 16
Number of passion fruits at first
= 6 u
= 6 x 16
= 96
Answer(s): 96
