At a fruit stall, there were
13 as many kiwis as mangoes. After 40 mangoes were sold, the number of kiwis became
34 as many as the mangoes. How many fruits were at the fruit stall at first?
|
Kiwis |
Mangoes |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
|
- 40 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of kiwis at first and in the end remains unchanged. Make the number of kiwis the same. LCM of 1 and 3 is 3.
Number of mangoes sold
= 9 u - 4 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 8
= 96
Answer(s): 96
