At a fruit stall, there were 1148 pears and mangoes at first.
16 of the pears and
18 of the mangoes were sold. In the end, there were same number of pears and mangoes. How many more pears than mangoes were sold?
| |
Pears |
Mangoes |
| Before |
6x7 =
42 u |
8x5 =
40 u |
| Change |
- 1x7 =
- 7 u
|
- 1x5 =
- 5 u
|
| After |
5x7 =
35 u |
7x5 =
35 u |
Comparing pears
and mangoes in the end |
1x35 =
35 u |
1x35 =
35 u |
The number of pears and mangoes in the end is the same. Make the number of pears and mangoes in the end the same. LCM of 5, 7 and 1 is 35.
Number of pears and mangoes in the end
= 42 u + 40 u
= 82 u
82 u = 1148
1 u = 1148 ÷ 82 = 14
Number of more pears than mangoes sold
= 7 u - 5 u
= 2 u
= 2 x 14
= 28
Answer(s): 28
