Question
Select the correct answerFather's age is 25 years more than the son’s age. Four years hence, father’s age will become 1 year less than thrice the son's age. What is father's present age?Options32 years34 years36 years38 years
Solution
Let's solve this step by step:
Step 1: Let's assume the son's present age is x years. Then the father's present age will be x + 25 years.
Step 2: According to the problem, four years hence (which means four years from now), the father’s age will be 1 year less than thrice the son's age. We can write this as an equation: (x + 25 + 4) = 3(x + 4) - 1.
Step 3: Simplify the equation: x + 29 = 3x + 12 - 1.
Step 4: Further simplify the equation: x + 29 = 3x + 11.
Step 5: Rearrange the equation to solve for x: 2x = 18.
Step 6: Solve for x: x = 9. This is the son's present age.
Step 7: Substitute x = 9 into the father's age equation: Father's age = x + 25 = 9 + 25 = 34 years.
So, the father's present age is 34 years. The correct answer is 34 years.
