A pen passing through two hands is finally sold at a profit of 44% of the original cost price. If the first dealer makes a profit of 20%, then the profit made by the second dealer is :

20%

Use direct concept of successive percentage = 

Successive  =  x + y + \(\frac{x × y}{100}\)

Successive =  20 + y + \(\frac{20 × y}{100}\) = 44%

y + \(\frac{20 × y}{100}\) = 24%

6y = 120%

y = 20%
