Given information:
Nirmal thinks of a number and subtracts 5/2 from it. He multiplies the result by 8. The result obtained is 3 times the same number he thought of.

Solution:
Let's assume the number Nirmal thought of is 'x'.

Step 1: Subtract 5/2 from the number
x - 5/2

Step 2: Multiply the result by 8
8(x - 5/2)

Step 3: The result is 3 times the number Nirmal thought of
8(x - 5/2) = 3x
Now, we can solve the equation:
8x - 20 = 3x
8x - 3x = 20
5x = 20
x = 20/5
x = 4
Therefore, the number Nirmal thought of is 4.
So, the correct answer is option A) 4.
