At a mart, the ratio of mangosteens to apples was 7 : 12. After Eva bought four-fifths of the apples, there was a total of 188 mangosteens and apples left at the mart. How many fruits were there at first?

Comparing mangosteens
and apples at first |
7x5 =
35 u |
12x5 =
60 u |
95 u |
Before |
|
5x12 =
60 u |
|
Change |
|
- 4x12 =
- 48 u |
|
After |
35 u |
1x12 =
12 u |
188 |
The number of apples at first is repeated. Make the number of apples at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 12 u
= 47 u
47 u = 188
1 u = 188 ÷ 47 = 4
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 4
= 380
Answer(s): 380
