At a fruit stall, there were 765 persimmons and starfruits at first.
35 of the persimmons and
18 of the starfruits were sold. In the end, there were same number of persimmons and starfruits. How many more persimmons than starfruits were sold?
| |
Persimmons |
Starfruits |
| Before |
5x7 =
35 u |
8x2 =
16 u |
| Change |
- 3x7 =
- 21 u
|
- 1x2 =
- 2 u
|
| After |
2x7 =
14 u |
7x2 =
14 u |
Comparing persimmons
and starfruits in the end |
1x14 =
14 u |
1x14 =
14 u |
The number of persimmons and starfruits in the end is the same. Make the number of persimmons and starfruits in the end the same. LCM of 2, 7 and 1 is 14.
Number of persimmons and starfruits in the end
= 35 u + 16 u
= 51 u
51 u = 765
1 u = 765 ÷ 51 = 15
Number of more persimmons than starfruits sold
= 21 u - 2 u
= 19 u
= 19 x 15
= 285
Answer(s): 285
