Given Data:
Amina thinks of a number and subtracts 5/2 from it. She multiplies the result by 8. The result obtained is 3 times the same number she thought of.

Let the number Amina thought of be x.

Calculations:
1. Amina subtracts 5/2 from the number:
x - 5/2
2. Amina multiplies the result by 8:
8(x - 5/2) = 3x
3. Solve the equation:
8x - 20 = 3x
8x - 3x = 20
5x = 20
x = 20/5
x = 4

Therefore, the number Amina thought of is 4.

Final Answer: The number is option c) 4.
