In a container, there are some starfruits and mangoes. If 108 mangoes are removed from the container, the percentage of mangoes will increase from 25% to 70%. How many mangoes are there in the container?
|
Starfruits |
Mangoes |
Before |
1x7 = 7 u |
3x7 = 21 u |
Change |
No change |
- 108 |
After |
7x1 = 7 u |
3x1 = 3 u |
25% =
25100 =
14 70% =
70100 =
710 The number of starfruits remains unchanged at first and in the end. Make the number of starfruits the same. LCM of 7 and 1 is 7.
Number of mangoes removed
= 21 u - 3 u
= 18 u
18 u = 108
1 u = 108 ÷ 18 = 6
Number of mangoes
= 21 u
= 21 x 6
= 126
Answer(s): 126
