Math Problem Statement

Ram’s father is thrice as old as Ram was 2 years ago. Five years from now, his father’s age will be 6 years more than twice Ram’s age. What is Ram's present age?

Solution

The problem given in the image states:

  • Ram's father was three times as old as Ram 2 years ago.
  • Five years from now, his father's age will be 6 years more than twice Ram's age.

We need to determine Ram's present age.

Let:

  • xx be Ram's current age.
  • yy be Ram's father's current age.

Step 1: Set up equations based on the problem

Condition 1 (2 years ago):

Two years ago, Ram's father was three times Ram's age: y2=3(x2)y - 2 = 3(x - 2) Simplifying this: y2=3x6y - 2 = 3x - 6 y=3x4(Equation 1)y = 3x - 4 \quad \text{(Equation 1)}

Condition 2 (5 years from now):

Five years from now, Ram's father will be 6 years more than twice Ram's age: y+5=2(x+5)+6y + 5 = 2(x + 5) + 6 Simplifying this: y+5=2x+10+6y + 5 = 2x + 10 + 6 y+5=2x+16y + 5 = 2x + 16 y=2x+11(Equation 2)y = 2x + 11 \quad \text{(Equation 2)}

Step 2: Solve the system of equations

Now, we have two equations:

  1. y=3x4y = 3x - 4
  2. y=2x+11y = 2x + 11

Equating these two expressions for yy: 3x4=2x+113x - 4 = 2x + 11 Solve for xx: 3x2x=11+43x - 2x = 11 + 4 x=15x = 15

Step 3: Find Ram's father's age

Using Equation 1: y=3(15)4=454=41y = 3(15) - 4 = 45 - 4 = 41

Conclusion:

Ram's current age is 15 years, and his father's current age is 41 years.
