Amina thinks of a number and subtracts 5/2 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?

Question

Vedant Borkar · Answer

Let us take the number as thought by Amina to be 'x'. First she subtracts 5/2 from it : x-(5/2) Then she multiplies it by 8: 8.{x-(5/2)} Finally the result is three times the original number: 8.{x-(5/2)}=3x 8x - 20=3x 5x=20 -------> X=4.
