There were 98 mangosteens and persimmons in a stall at first. After
14 of the mangosteens and
12 of the persimmons were sold, there were a total of 65 mangosteens and persimmons now. How many mangosteens are there now?

Total |
| Before |
4 u |
2 p |
98 |
| Change |
- 1 u |
- 1 p |
- 33 |
| After |
3 u |
1 p |
65 |
Total number of mangosteens and persimmons sold
= 98 - 65
= 33
3 u + 1 p = 65
1 p = 65 - 3 u --- (1)
1 u + 1 p = 33
1 p = 33 - 1 u --- (2)
(2) = (1)
33 - 1 u = 65 - 3 u
3 u - 1 u = 65 - 33
2 u = 32
1 u = 32 ÷ 2 = 16
Number of mangosteens now
= 3 u
= 3 x 16
= 48
Answer(s): 48
