Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: If Alice has 60 pens, Clara 2 / 5 * 60 = 24 pens. The number of pens that Alice has more than Clara is 60 - 24 = 36. Since Alice is 20, and the number of pens that Alice has more than Clara is their age difference, Clara is 20 + 36 = 56 years old. In five years, Clara's age will be 56 + 5 = 61 years.
The question and answer:
The difference in the number of pens that Alice and Clara each have matches their age difference. Alice has 60 pens and Clara has 2/5 times as many pens as Alice. If Alice's age is 20 and Clara is older than Alice, calculate Clara's age in 5 years to come.
The answer is 61
