Question:

Amina thinks of a number and subtracts 52 from it. She multiplies the result by 8. The result now obtained is 3 times the same number she thought of. What is the number?

Let the number be x.
As per the question, 8(x - 52) = 3x
8x - 416 = 3x
8x - 3x = 416
5x = 416
x = 416/5
x = 83.2
Number is 83.2
