| 1. Newspaper... | Rs. 6/- |
| 2. Iron... | Rs. 14/- |
| 3. Brass... | Rs. 180/- |
| 4. Plastic... | Rs. 12/- |
| 5. Water paper... | Rs. 4.50/- |
How much money will Dinu pay for 32 kg iron?
उत्तर
1 kg of plastic is sold in Rs 14
Therefore, 32 kg of plastic = Rs 14 × 32 = Rs 448.
This can be calculated in a similar manner-
| 30 | 2 | |
| 10 | 30 × 10 | 2 × 10 |
| 300 | 20 | |
| 4 | 30 × 4 | 2 × 4 |
| 120 | 8 |
You can get the desired numbers by adding the numbers in bold
300 + 20 + 120 + 8 = 448
So, Dinu will pay Rs 448 for 32 kg of plastic.
