Solution
(1) Kiran bought 1 kg plastic for Rs 10 and sold 1 kg plastic for Rs 12.
So, she earn Rs 12 - Rs 10 = Rs 2.
(2) For 1 kg plastic she earns Rs 2.
Therefore, for 63 kg plastic she earns = Rs 2 × 63 = Rs 126
It can be calculated as follows:
| 60 | 3 | |
| 2 | 60 × 2 | 3 × 2 |
| 120 | 6 |
You will get 126 by adding the digits in the last row.
