Here is the solution:

----------------------------------------

Selling Price = Rs 150 (Given)

Profit = 20% (Given)


Find the Selling Price Percentage:

Selling Price = Cost Price + Profit

Selling Price = 100 + 20

Selling Price = 120%


Find the cost price of the book:

Selling Price Percentage = 120%

Selling Price = Rs 150

120% = Rs 150

1% = 150 ÷ 120 = Rs 1.125

100% = 12.50 x 100

100% = Rs 125

Cost Price = Rs 125


Find the selling price if he wants to gain 25%:

25% discount = 0.25 x 125 = Rs 31.25

New Selling Price = 125 - 31.25

New Selling Price  = Rs 156.25


Answer: The selling price is Rs 156.25

Given, Selling price = 150, gain = 20%.

We know that Cost price = (100/(100 + Gain%)) * SP

                                         = (100/(120)) * 150

                                        = 125.


So, cost price = 125.

Given Gain = 25%.

We know that Selling price = [(100 + Gain%)/100] * CP

                                             = [(100 + 25)/100] * 125

                                             = [(125/100)] * 125

                                             = 156.25.



Hope this helps!
