Step-by-step explanation:
4 pencil = 32
1 pencil = 32/4 = 8
10 pencil = 8×10 = 80
6 notebook = 60
1 notebook = 60/6 = 10
9 notebooks = 10×9 = 90
7m cloth = 3294
1m cloth = 3294/7 = 470.57
6m cloth = 470.57 × 6 = 2823.42
9 kg rice = 810
1 kg rice = 810/9 = 90
50 kg rice = 90 × 50 = 4500
72 books = 9 kg
1 book = 9/72
30 book = 9/72 × 30 = 3.75
5 pens = 115
1 pen = 115/5 = 23
2302 = 2302/23 = 100
12 soup = 1200
1 soup = 1200/12 = 100
5 soup = 100 × 5 = 500
