Since 264 ÷ 4 = 66
Therefore, the long wooden panels are sufficient for 66 bookshelves.
306 ÷ 8 = 38 and remainder 2.
So, the short wooden panels are sufficient 38 bookshelves.
2400 ÷ 16 = 150 and remainder 2.
So, the small clips are sufficient for 150 bookshelves
120 ÷ 4 = 30
So, large clips are sufficient for 30 bookshelves 2800 ÷ 32 = 87 and remainder 16.
So, screws are sufficient for 87 bookshelves. Based on the above data the carpenter can make 30 bookshelves.

Munshi Lai has a big farm in Bihar. Every Saturday, he sells the vegetables from his farm at Sundar Sabzi Mandi. Munshi ji maintains a detailed record of the quantity of vegetables he sends to the Mandi and the cost of each vegetable. The following table shows his record book on one Saturday.
His naughty grandson has erased some numbers from his record book. Help Munshi Lai complete the table.
Solution:
Let Us Solve
Divide the following. Try dividing using place values, whenever you can. Identify the remainder, if any, and check whether N = D × Q + R.
1. 506 ÷ 5
Solution:
N = 506, D = 5, Q = 101, R = 1
5 × 101 + 1 = 505 + 1 = 506
Therefore, N = D × Q + R
2. 918 ÷ 8
Solution:
N = 918, D = 8, Q = 114, R = 6
8 × 114 + 6 = 912 + 6 = 918
Therefore, N = D × Q + R
3. 8,126 ÷ 7
Solution:
N = 8126, D = 7, Q = 1160, R = 6
7 × 1160 + 6 = 8120 + 6 = 8126
Therefore, N = D × Q + R
4. 9,324 ÷ 4
Solution:
N = 9324, D = 4, Q = 233, R = 0
Therefore, N = D × Q + R
5. 876 ÷ 6
Solution:
N = 876, D = 6, Q = 146, R = 0
Therefore, N = D × Q + R
6. 7,008 ÷ 3
Solution:
N = 9324, D = 4, Q = 233, R = 0
Therefore, N = D × Q + R
7. 934 ÷ 12
Solution:
N = 934, D = 12, Q = 77, R = 10
12 × 77 + 10 = 924 + 10 = 934
Therefore, N = D × Q + R
8. 829 ÷ 23
Solution:
N = 829, D = 23, Q = 36, R = 1
23 × 36 + 1 = 828 + 1 = 829
Therefore, N = D × Q + R
9. 705 ÷ 18
Solution:
N = 705, D = 18, Q = 39, R = 3
18 × 39 + 3 = 702 + 3 = 705
Therefore, N = D × Q + R
10. 8,704 ÷ 32
Solution:
N = 705, D = 18, Q = 39, R = 3
Therefore, N = D × Q + R
11. 6,790 ÷ 45
Solution:
N = 6790, D = 45, Q = 150, R = 40
45 × 150 + 40 = 6750 + 40 = 6790
Therefore, N = D × Q + R
12. 5,074 ÷ 21
Solution:
N = 5074, D = 21, Q = 241, R = 13
21 × 241 + 13 = 5074
Therefore, N = D × Q + R
