A pencil costs two and half rupees. Amit buys one and a half dozen pen...
Given Information:
- Cost of one pencil is 2.5 rupees.
- Amit buys 1.5 dozen pencils.
- Amit gives a 100 rupee note to the shopkeeper.

Calculation:
To find out the money Amit will get back, we need to calculate the cost of 1.5 dozen pencils and subtract it from the 100 rupee note.

Calculation of the cost of 1.5 dozen pencils:
- 1 dozen pencils = 12 pencils
- Cost of 1 dozen pencils = 2.5 rupees/pencil * 12 pencils = 30 rupees
- Cost of 1.5 dozen pencils = 1.5 * 30 rupees = 45 rupees

Calculation of the money Amit will get back:
- Money Amit gave to the shopkeeper = 100 rupees
- Cost of 1.5 dozen pencils = 45 rupees
- Money Amit will get back = 100 rupees - 45 rupees = 55 rupees

Therefore, the correct answer is option 'D' - 55 rupees.
