4. 38473.  By adding 14852 and 10001, we get the sum as  24853. Now adding this sum to 13620, we get our answer 38473.

5. 74825

2. State whether each of the following statement is True or False:

1. True. when we add 2346 and 6432, the sum we get is 8778.

2. True. 9999 + 99999 = 109998 + 999 = 110997.

3. True.

4. True. 51 + 0 = 51

5. True. 360928 + 65035 = 425963

3. (d) 263700
Explanation: 86325 + 69770 + 107605 = 263700. They have asked us to find the total number of bulbs produced in 3 months. So we have to add the number of bulbs produced in January, February, and March to find the solution.
4. (b) The number itself
Explanation: Because 0 is the additive identity. That means when we add any number to 0, the sum will be number itself.
For example: 100 + 0 = 100 ; 5 + 0 = 5
5. (d) 15,57,620
Explanation: 15,57,620 is the correct answer.
Total cutleries = 267136 + 501243 + 789241 = 15,57,620
6. (b) 999
Explanation: 999 is the correct answer.
2567853 + 999 = _____ + 2567853 _____ = 2567853 + 999 - 2567853 _____ = 999
7. (c) 102000
Explanation: 102000 is the correct answer.
101000 + 1000 = 102000
8. (a) - (iv), (b) - (iii), (c) - (ii), (d) - (i)

1.

10. Number of dolls made by the machine = 713082
Number of teddy bears made by the machine = 264529
Total number of toys made by the machine = 713082 + 264529

The total number of toys made by the machine is 977611.

11. Number of bikes manufactured in the month of January = 57612
Number of bikes manufactured in the month of February = 26789
Total bikes manufactured = 57612 +26789

Total bikes manufactured in the month of January and February is 84401.

12. Number of men = 15896
Number of women = 12458
Number of children = 20015
Total number of people = 12458 + 20015 + 20015

48369 people visited the exhibition on Sunday.

1. Number of spectators in the first match = 64000
Number of spectators in the second match = 48000
Number of spectators in the third match = 52500
total number of spectators  = 64000 + 48000 + 52500

164500 spectators came in all the three shows in the stadium
2. Number of children in the first show = 12505
Number of children in the second show = 10275
Total number of children = 12505 + 10275
