In a basket,
13 are pomegranates and the rest are pears. If I give away 40 pears, there will be
211 as many pears as pomegranates. How many pomegranates and pears are there in the basket altogether?
|
Pomegranates |
Pears |
Total |
Before |
1x11 = 11 u |
2x11 = 22 u |
3x11 = 33 u |
Change |
|
- 40 |
|
After |
11x1 = 11 u |
2x1 = 2 u |
|
The number of pomegranates remains unchanged.
Change in the number of pears
= 22 u - 2 u
= 20 u
20 u = 40
1 u = 40 ÷ 20 = 2
Number of pomegranates and pears
= 33 u
= 33 x 2
= 66
Answer(s): 66
