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

Pomegranates |
Mangoes |
Total |
| Before |
4 u |
11 u |
15 u |
| Change |
- 3.2 u |
- 47 |
|
| After |
0.8 u |
1.6 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 mangoes left
= 2 x 0.8 u
= 1.6 u
Number of mangoes sold
= 11 u - 1.6 u
= 9.4 u
9.4 u = 47
1 u = 47 ÷ 9.4 = 5
Number of pomegranates and mangoes at first
= 4 u + 11 u
= 15 u
= 15 x 5
= 75
Answer(s): 75
