Q.2

A city has a population of 37,04,926. If this includes 11,24,069 men and 10,96,478 women.

What is the number of children in the city?

Answer:

The population of a city including all

=37,04,926

Number of mens in the city: 11,24,069

Number of womens in the city:10,96,478

   1 1 2 4 0 6 9

+ 1 0 9 6 4 7 8

   2 2 2 0 5 4 7        (No.mens & womens 

                                                    together)

To find number of children in the city,

Let us subtract no. mens and womens from the Overall population of the city.

       3 7 0 4 9 2 6

    -  2 2 2 0 5 4 7

       1 4 8 4 3 7 9

Therefore, The number of childrens in the city = 14,84,379

Let us verify our answer

Population of the city: 37,04,926

            No.of males     :  1 1 2 4 0 6 9

            No.of females :   1 0 9 6 4 7 8 

      +    No.of children :   1 4 8 4 3 7 9

                                           3 7 0 4 9 2 6

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
