The correct Answer is:
To determine Veer's age after two years, we will analyze the two statements provided: ### Given: - We need to find Veer's age after 2 years. ### Statement I: - The average age of Abhimanyu and Kumar is 36 years. - The ratio of Kumar's age to Patel's age is 1:2. From the first part of Statement I, we can derive that the total age of Abhimanyu and Kumar combined is: \[ \text{Average} = \frac{\text{Age of Abhimanyu} + \text{Age of Kumar}}{2} \] \[ 36 = \frac{A + K}{2} \implies A + K = 72 \quad \text{(1)} \] From the second part, if Kumar's age is \( K \), then Patel's age \( P \) can be expressed as: \[ \frac{K}{P} = \frac{1}{2} \implies P = 2K \quad \text{(2)} \] However, we cannot determine Veer's age from this information alone, as we do not have any direct information about Veer's age or a relationship involving Veer. ### Statement II: - The age of Patel is two years more than the age of Veer. - The average age of Patel and Abhimanyu is 48 years. From the first part of Statement II, we can express Patel's age \( P \) in terms of Veer's age \( V \): \[ P = V + 2 \quad \text{(3)} \] From the second part, we can derive the total age of Patel and Abhimanyu: \[ \text{Average} = \frac{P + A}{2} = 48 \implies P + A = 96 \quad \text{(4)} \] Now, substituting equation (3) into equation (4): \[ (V + 2) + A = 96 \implies A + V = 94 \quad \text{(5)} \] From equation (5), we can express Veer's age in terms of Abhimanyu's age: \[ V = 94 - A \quad \text{(6)} \] ### Conclusion: Now, we have two statements: - Statement I does not provide sufficient information to determine Veer's age. - Statement II provides a relationship that allows us to express Veer's age in terms of Abhimanyu's age. However, we still need to know the value of \( A \) (Abhimanyu's age) to find Veer's age directly. Therefore, we cannot determine Veer's age with either statement alone. ### Final Answer: Both statements together are necessary to find Veer's age after two years.
