At a fruit stall, there were 1020 apples and kiwis at first.
35 of the apples and
18 of the kiwis were sold. In the end, there were same number of apples and kiwis. How many less kiwis than apples were sold?
| |
Apples |
Kiwis |
| Before |
5x7 =
35 u |
8x2 =
16 u |
| Change |
- 3x7 =
- 21 u
|
- 1x2 =
- 2 u
|
| After |
2x7 =
14 u |
7x2 =
14 u |
Comparing apples
and kiwis in the end |
1x14 =
14 u |
1x14 =
14 u |
The number of apples and kiwis in the end is the same. Make the number of apples and kiwis in the end the same. LCM of 2, 7 and 1 is 14.
Number of apples and kiwis in the end
= 35 u + 16 u
= 51 u
51 u = 1020
1 u = 1020 ÷ 51 = 20
Number of less kiwis than apples were sold
= 21 u - 2 u
= 19 u
= 19 x 20
= 380
Answer(s): 380
