A salesman enters the quantity sold and the price into the computer. Both the numbers are two-digit numbers. But, by mistake, both the numbers were entered with their digits interchanged. The total sales value remained the same, i.e. Rs. $1,148$, but the inventory reduced by $54$. What is the actual price per piece?

  1. $\text{Rs. }82$
  2. $\text{Rs. }41$
  3. $\text{Rs. }6$
  4. $\text{Rs. }28$
