Bobby had mangoes and pears. The ratio of mangoes to pears was 6 : 5. After
34 of the mangoes and 18 pears were sold, there were 3 times as many mangoes as pears left. How many mangoes and pears were there at first?
| |
Mangoes |
Pears |
Comparing mangoes
and pears at first |
6x2 =
12 u |
5x2 =
10 u |
| Before |
4x3 =
12 u |
|
| Change |
- 3x3 =
- 9 u |
- 18 |
| After |
1x3 =
3 u |
|
Comparing mangoes
and pears in the end |
3 u |
1 u |
The number of mangoes at first is repeated. Make the number of mangoes at first the same. LCM of 6 and 4 is 12.
Number of pears sold
= 10 u - 1 u
= 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Number of mangoes and pears at first
= 12 u + 10 u
= 22 u
= 22 x 2
= 44
Answer(s): 44
