| Before |
4 u |
11 u |
15 u |
| Change |
- 3.2 u |
- 129 |
|
| After |
0.8 u |
2.4 u |
|
Number of mangoes sold
=
45 x 4 u
= 3.2 u
Number of mangoes left
= 4 u - 3.2 u
= 0.8 u
Number of passion fruits left
= 3 x 0.8 u
= 2.4 u
Number of passion fruits sold
= 11 u - 2.4 u
= 8.6 u
8.6 u = 129
1 u = 129 ÷ 8.6 = 15
Number of mangoes and passion fruits at first
= 4 u + 11 u
= 15 u
= 15 x 15
= 225
Answer(s): 225
