Problem Set No.13 Mixed examples- addition & subtraction (Std.V)

Q.1.The Forest Department planted 23,078 trees of khair,   19,476 of behada besides trees of several other kinds.
If the department planted 50,000 trees altogether, How many trees were neither of khair nor of behada?

Answer:

---------------------------------------------------
Answer:

No.of khair trees    :      2 3 0 7 8
No.of behada trees :      1 9 4 7 6

No.of khair & behada trees together

            2 3 0 7 8
       +   1 9 4 7 6    
            4 2 5 5 4

No.of khair & behada trees together = 42554

Forest Department planted 50,000 trees altogether out of which 23,078 trees are of khair and 19476 trees are of behada.

To find number of trees other than khair and behada.

Total No.of trees      :        5 0 0 0 0
No.Khair & behada   :        4 2 5 5 4
trees together 

                        5 0 0 0 0
                     -  4 2 5 5 4
                           7 4 4 6

Therefore,The number of trees other than khair and behada are 7446.

Let us verify our answer,
Total number plants 50000
Therefore,
No.of Khair plants     :     2 3 0 7 8
No.of Behada plants :     1 9 4 7 6
No.of other plants     :        7 4 4 6
Overall Total               :     5 0 0 0 0
