At a fruit stall, there were 646 mangoes and kiwis at first.
14 of the mangoes and
16 of the kiwis were sold. In the end, there were same number of mangoes and kiwis. How many less kiwis than mangoes were sold?
| |
Mangoes |
Kiwis |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing mangoes
and kiwis in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of mangoes and kiwis in the end is the same. Make the number of mangoes and kiwis in the end the same. LCM of 3, 5 and 1 is 15.
Number of mangoes and kiwis in the end
= 20 u + 18 u
= 38 u
38 u = 646
1 u = 646 ÷ 38 = 17
Number of less kiwis than mangoes were sold
= 5 u - 3 u
= 2 u
= 2 x 17
= 34
Answer(s): 34
