Question

A trader increases the selling price by 20% because of whic the profit percent increases from 10% to 15% what is the percentage change in c.p?

Answer 1

100 (Initial CP) ---- 20% ↑(initial profit)---> 120 (SP).
120 (SP) ---25%↑ ---> 150 (New SP).
Let x be the new Cost price.
Selling Price = 150.
x * 1.25 = 150.
x = 120.
% change = [(120 -100)/ 100] *100 = 20%.

Answer 2

Answer:

cp increased by 14.78%.

Step-by-step explanation:

Let cp 100, profit is 10%

so sp 110

• Sp increased by 20%

new sp = 110×120/100 = 132

• 132 is equivalent to 115 ( 15% profit )

CP= 132/115×100 = 114.78

so cp increased by 14.78%.
