Thrice a number decreased by 5 exceeds twice the number by 1. Find the number.

Answer :

Let the number be x. Then, thrice the number = 3x and twice of this number = 2x.


If we decrease thrice of x by 5, we get (3x – 5).


According to the question,


(3x – 5) – 2x = 1


3x – 5 –2x = 1


x – 5 = 1


x = 1 + 5


x = 6


Hence, the required number is 6.
