Answer:
Let the cost price be Rs. 100x
20% profit means selling price is Rs. 120x.
New cost price = Rs. (100x+50)
New selling price = Rs. (120x+30)
New profit =(120x+30)−(100x+50)= Rs. 20x−20
20% less 10/3 % = 50/3 %
20x-20/100x+50=50 X 100/3 = 1/6
On cross multiplying, we have
120x−120=100x+50
⇒20x=170
⇒x=8.5
Therefore, cost price is Rs. 850.
