A person is to count 4500 currency notes. Let \( \mathrm{a}_{\mathrm{n}} \) denotes the number of notes he counts in the \( \mathrm{n}^{\text {th }} \) minute. If \( \mathrm{a}_{1}=\mathrm{a}_{2}=\ldots=\mathrm{a}_{10}=150 \) and \( \mathrm{a}_{10}, \mathrm{a}_{11} \ldots \) are in \( \mathrm{AP} \) with common difference \( -2 \), then the timehttps://bit.ly/YTAI_PWAP https://www.pw.live
