In a basket,
12 are pears and the rest are mangosteens. If I give away 10 mangosteens, there will be
34 as many mangosteens as pears. How many pears and mangosteens are there in the basket altogether?

Pears |
Mangosteens |
Total |
| Before |
1x4 =
4 u |
1x4 =
4 u |
2x4 =
8 u |
| Change |
|
- 10 |
|
| After |
4x1 =
4 u |
3x1 =
3 u |
|
The number of pears remains unchanged.
Change in the number of mangosteens
= 4 u - 3 u
= 1 u
1 u = 10
1 u = 10 ÷ 1 = 10
Number of pears and mangosteens
= 8 u
= 8 x 10
= 80
Answer(s): 80
