Let the marked price of the item be x.
The cost price is Rs. 150.
Harish gives a 20% discount on the marked price, so the selling price is 80% of the marked price.
Since there is no profit and no loss, the selling price is equal to the cost price. Thus, we can write the equation:
\[ \text{Selling price} = 80\% \times \text{Marked price} = 150 \]
Simplifying the equation:
\[ 0.8x = 150 \] Solving for x: \[ x = \frac{150}{0.8} = 187.5 \]
The marked price of the item is Rs. 187.5.
The correct answer is (a) Rs. 187.5.
