Answer: Option (A)
Step-by-step explanation:
Let the original price of the clock be "x "
<em>The clock is then resold to a collector = x + 20% of "x "</em>
<em>= x + 0.2x</em>
<em>= 1.2x</em>
Now, the shop re-buy the clock at a price = <em></em>
<em></em>
<em>= 0.6x </em>
Therefore,
<em>Original Cost - Buy-Back price = $100</em>
<em>⇒ x - 0.6x = 100</em>
<em>⇒ x = 250 </em>
Hence , the selling price of the clock for the second time is
<em></em>
<em>= $270 </em>
