34 x 40 = 30
40 - 30 = 10

25 The number of persimmons is 25 less than the number of oranges in the end. So, if another 25 persimmons are added, the number of persimmons and oranges in the end will be the same.
5 u + 10 + 25 = 12 u
5 u + 35 = 12 u
12 u - 5 u = 35
7 u = 35
1 u = 35 ÷ 7 = 5
Number of oranges left
= 12 u
= 12 x 5
= 60
Total number of fruits left
= 5 u + 10 + 12 u
= 17 u + 10
= 17 x 5 + 10
= 85 + 10
= 95
