At a fruit stall, there were 1230 mangoes and passion fruits at first.
16 of the mangoes and
18 of the passion fruits were sold. In the end, there were same number of mangoes and passion fruits. How many less passion fruits than mangoes were sold?

Mangoes |
Passion Fruits |
| Before |
6x7 =
42 u |
8x5 =
40 u |
| Change |
- 1x7 =
- 7 u
|
- 1x5 =
- 5 u
|
| After |
5x7 =
35 u |
7x5 =
35 u |
Comparing mangoes
and passion fruits in the end |
1x35 =
35 u |
1x35 =
35 u |
The number of mangoes and passion fruits in the end is the same. Make the number of mangoes and passion fruits in the end the same. LCM of 5, 7 and 1 is 35.
Number of mangoes and passion fruits in the end
= 42 u + 40 u
= 82 u
82 u = 1230
1 u = 1230 ÷ 82 = 15
Number of less passion fruits than mangoes were sold
= 7 u - 5 u
= 2 u
= 2 x 15
= 30
Answer(s): 30
