In a basket,
14 are apples and the rest are lemons. If I give away 620 lemons, there will be
211 as many lemons as apples. How many apples and lemons are there in the basket altogether?
|
Apples |
Lemons |
Total |
Before |
1x11 = 11 u |
3x11 = 33 u |
4x11 = 44 u |
Change |
|
- 620 |
|
After |
11x1 = 11 u |
2x1 = 2 u |
|
The number of apples remains unchanged.
Change in the number of lemons
= 33 u - 2 u
= 31 u
31 u = 620
1 u = 620 ÷ 31 = 20
Number of apples and lemons
= 44 u
= 44 x 20
= 880
Answer(s): 880
