There were 82 mangoes and oranges in a stall at first. After
14 of the mangoes and
12 of the oranges were sold, there were a total of 56 mangoes and oranges now. How many mangoes were there at first?

Total |
| Before |
4 u |
2 p |
82 |
| Change |
- 1 u |
- 1 p |
- 26 |
| After |
3 u |
1 p |
56 |
Total number of mangoes and oranges sold
= 82 - 56
= 26
3 u + 1 p = 56
1 p = 56 - 3 u --- (1)
1 u + 1 p = 26
1 p = 26 - 1 u --- (2)
(2) = (1)
26 - 1 u = 56 - 3 u
3 u - 1 u = 56 - 26
2 u = 30
1 u = 30 ÷ 2 = 15
Number of mangoes at first
= 4 u
= 4 x 15
= 60
Answer(s): 60
