Solution
1 kg of iron is sold in Rs 14
Therefore, 32 kg of iron = 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 iron.
