Answer 2

Answer:

The exact age of Giya can not determined with the given information.

Explanation:

We know the following,

• Giya's age is the ages of Amit and Bob combined.
• 15 years back, Bob had the same age of Amit.

But,

• We do not know that what was Amit's age exactly 15 years ago. So, even if we assume his age, we can never assume the exact number.
• Similarly, if we do not know Amit and Bob's ages it is impossible to conclude a number.
• Thus, if we do not know the numbers, we will never be able to guess Giya's age.

Hence, we can conclude that Giya's age can not be guessed. We can not determine the answer from either of the statements as well as combination of these.
