The cost price of an item is Rs.120 and the profit percentage is (x+30)% of the cost price. If the cost price is increased by 25% and selling price remains same the profit percentage is (x-20)% . Find the value of x.

120

105

Explanation:

Profit on item = (x+30)% of 120
SP = (x+30)% of 120+120
New CP = (100+25)% of 120 = Rs.150
SP = 150 + (x-20)% of 150 (x+30)% * 120 + 120

= 150 + (x-20)% of 150
=> 12x + 360 – 15x + 300 = 300
=> x = 120

Hence, option 1 is the correct answer.
