1 1/2 lbs

Let's calculate the amount of strawberries
each person will eat:
• Rishi's younger sister will eat half as much as the others. So, she will eat (1/2) * (1 1/2) = 3/4 pounds of strawberries.
• Rishi's other sister will eat the same amount as Rishi. Therefore, she will eat 1 1/2 pounds of strawberries.
Now, let's calculate how much Rishi will eat: Rishi's younger sister: 3/4 pounds
Rishi's other sister: 1 1/2 pounds
So, Rishi will eat 1 1/2 pounds of strawberries.
Therefore, Rishi will eat 1 1/2 pounds of strawberries.
