At a fruit stall, there were 190 kiwis and mangoes at first.
14 of the kiwis and
16 of the mangoes were sold. In the end, there were same number of kiwis and mangoes. How many less mangoes than kiwis were sold?
| |
Kiwis |
Mangoes |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing kiwis
and mangoes in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of kiwis and mangoes in the end is the same. Make the number of kiwis and mangoes in the end the same. LCM of 3, 5 and 1 is 15.
Number of kiwis and mangoes in the end
= 20 u + 18 u
= 38 u
38 u = 190
1 u = 190 ÷ 38 = 5
Number of less mangoes than kiwis were sold
= 5 u - 3 u
= 2 u
= 2 x 5
= 10
Answer(s): 10
