A fruit seller had pomegranates and lemons. The ratio of pomegranates to lemons was 4 : 11. After

Pomegranates |
Lemons |
Total |
| Before |
4 u |
11 u |
15 u |
| Change |
- 3.2 u |
- 117 |
|
| After |
0.8 u |
3.2 u |
|
Number of pomegranates sold
=
45 x 4 u
= 3.2 u
Number of pomegranates left
= 4 u - 3.2 u
= 0.8 u
Number of lemons left
= 4 x 0.8 u
= 3.2 u
Number of lemons sold
= 11 u - 3.2 u
= 7.8 u
7.8 u = 117
1 u = 117 ÷ 7.8 = 15
Number of pomegranates and lemons at first
= 4 u + 11 u
= 15 u
= 15 x 15
= 225
Answer(s): 225
