Question
elect the correct answerA person was asked to state his age in years. His reply was, “Take my age three years hence, multiply it by 3 and then subtract three times my age three years ago and you will know how old I am.” What was the age of the person?Options24 years32 years.18 years20 years
Solution
Let's denote the current age of the person as x.
According to the problem, the equation is: 3*(x+3) - 3*(x-3) = x
Solving this equation step by step:
Step 1: Distribute the 3 in both terms: 3x + 9 - 3x + 9 = x Step 2: Simplify the equation: 18 = x
So, the person is 18 years old.
