Given Data:
- The ratio between the ages of a and b is 7:5.
- 9 years ago, their ages were in the ratio of 2:3.
Let's solve the problem step by step:
Step 1: Setting up equations
Let's assume the present ages of a and b are 7x and 5x, respectively.
According to the second statement, 9 years ago, their ages were 2x and 3x, respectively.
Step 2: Using the given ratios to form equations
- From the first statement:
7x - 9 = 2x
5x - 9 = 3x
Step 3: Solving the equations
- Solving the first equation:
7x - 2x = 9
5x = 9
x = 9/5
x = 1.8
Step 4: Finding their present ages
- Substituting the value of x back into the equations:
a's age = 7 * 1.8 = 12.6 years
b's age = 5 * 1.8 = 9 years
Conclusion:
- Therefore, the present age of a is 12.6 years and the present age of b is 9 years.
- The ratio between the ages of a and b is 7:5.
- 9 years ago, their ages were in the ratio of 2:3.
