A Correct answer
Explanation

Let the number of notes be x, x, and 2x. Total value = 20x + 50x + 5(2x) = 80x. Since total value is 80, 80x = 80, so x = 1. The number of Rs. 50 notes is x = 1.

AI explanation

Let the number of Rs. 20, Rs. 50 and Rs. 5 notes be x, x and 2x respectively. The total amount paid is 20x + 50x + 5(2x) = 80x. Given the total amount is Rs. 80, we have 80x = 80, which means x = 1. The number of Rs. 50 notes is x, which is 1.
