At a fruit stall, there were 988 mangoes and oranges at first.
14 of the mangoes and
18 of the oranges were sold. In the end, there were same number of mangoes and oranges. How many less oranges than mangoes were sold?
| |
Mangoes |
Oranges |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing mangoes
and oranges in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of mangoes and oranges in the end is the same. Make the number of mangoes and oranges in the end the same. LCM of 3, 7 and 1 is 21.
Number of mangoes and oranges in the end
= 28 u + 24 u
= 52 u
52 u = 988
1 u = 988 ÷ 52 = 19
Number of less oranges than mangoes were sold
= 7 u - 3 u
= 4 u
= 4 x 19
= 76
Answer(s): 76
