Question IV. Do the following
1. In a school library, there are 875 English books and 527 Hindi books. Find the total number of books in the library ?
2. In a school there are 5325 boys and 3195 girls. How many students are there in all ?
3. The gardener at the rose garden planted 205 red rose saplings and 335 yellow rose saplings. How many rose saplings did he plant in all ?
4. Mohit sold 100 ice creams. Rahul sold 205 ice creams. Mohan sold 150 ice creams. How many ice-creams were sold in all ?
5. At a railway station, 2380 tickets were sold on first week and 3605 tickets on second week. How many tickets were sold on both weeks ?
6. In the school library, there are 2999 books for primary school children and 3500 books for middle school children. How many books are there in all ?
7. A fruit seller has 620 apples, 400 mangoes and 98 oranges. How many fruits are there in all ?
8. At the book fair, 451 books were sold on the first day and 398 books on the second day. How many books were sold in all ?
Answer:
1. Quantity of English publications = 875
Quantity of Hindi publications = 527
Combined count of books = 875 + 527 = 1402
Hence, there are exactly 1402 books stored in the library.

2. Count of boys in the school = 5325
Count of girls in the school = 3195
Whole number of children = 5325 + 3195 = 8520
Thus, there are 8520 students enrolled in total.

3. Red rose plants = 205
Yellow rose plants = 335
All plants together = 205 + 335 = 540
So, the worker planted a total of 540 saplings in the garden.

4. Ice creams sold by Mohit = 100
Ice creams sold by Rahul = 205
Ice creams sold by Mohan = 150
Entire count of sold ice creams = 100 + 205 + 150 = 455
Therefore, a grand total of 455 treats were sold.

5. Tickets purchased in week one = 2380
Tickets purchased in week two = 3605
Combined sales for both weeks = 2380 + 3605 = 5985
So, 5985 passenger tickets were bought during those two weeks.

6. Reading materials for primary classes = 2999
Reading materials for middle classes = 3500
Total reading materials available = 2999 + 3500 = 6499
Hence, there is a total collection of 6499 books.

7. Quantity of apples = 620
Quantity of mangoes = 400
Quantity of oranges = 98
Entire sum of all fruits = 620 + 400 + 98 = 1118
Therefore, the shopkeeper has 1118 pieces of fruit altogether.

8. Books bought on day one = 451
Books bought on day two = 398
Grand total of sales = 451 + 398 = 849
Thus, the total amount of books sold stands at 849.
In simple words: This section contains word problems. We read the story carefully, find the key numbers, and add them up to find the total.

Exam Tip: Look out for signal words like "total", "in all", or "both" because they usually mean you need to perform addition.
