Ben had guavas and mangoes. The ratio of guavas to mangoes was 8 : 3. After
14 of the guavas and 8 mangoes were sold, there were 6 times as many guavas as mangoes left. How many guavas and mangoes were sold?
| |
Guavas |
Mangoes |
Comparing guavas
and mangoes at first |
8x1 =
8 u |
3x1 =
3 u |
| Before |
4x2 =
8 u |
|
| Change |
- 1x2 =
- 2 u |
- 8 |
| After |
3x2 =
6 u |
|
Comparing guavas
and mangoes in the end |
6 u |
1 u |
The number of guavas at first is repeated. Make the number of guavas at first the same. LCM of 8 and 4 is 8.
Number of mangoes sold
= 3 u - 1 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Number of guavas and mangoes sold
= 2 u + 8
= 2 x 4 + 8
= 8 + 8
= 16
Answer(s): 16
