In a basket,
13 are lemons and the rest are pears. If I give away 112 pears, there will be
25 as many pears as lemons. How many lemons and pears are there in the basket altogether?
|
Lemons |
Pears |
Total |
Before |
1x5 = 5 u |
2x5 = 10 u |
3x5 = 15 u |
Change |
|
- 112 |
|
After |
5x1 = 5 u |
2x1 = 2 u |
|
The number of lemons remains unchanged.
Change in the number of pears
= 10 u - 2 u
= 8 u
8 u = 112
1 u = 112 ÷ 8 = 14
Number of lemons and pears
= 15 u
= 15 x 14
= 210
Answer(s): 210
