Direct Answer
The field trial scale has been explicitly set at one billion pieces for each of the selected denominations (₹10 and ₹20) to ensure a sufficiently large sample size across diverse conditions
Volume Calculation for Trial:Step 1: ₹10 Denomination = 1,000,000,000 (One Billion) pieces.Step 2: ₹20 Denomination = 1,000,000,000 (One Billion) pieces.Total Output: 2 Billion polymer notes will be injected into the trial ecosystem.
