Noman sells pens for TK. 65.00 each. This price gives him a profit of 30 percent on the costs. What will be the new retail price of each pen if he cuts his profit to 10 percent of costs ?
A
TK. 52.00
B
TK. 71.50
C
TK. 58.50
D
TK. 55.00
Correct Answer: TK. 55.00
Let the cost price be A. Then, A + 30% of A = 65 or, A + 0.3A = 65 or, 1.3A = 65 or, A = 65 / 1.3 = 50 TK. New retail price at 10% profit = 50 + 10% of 50 = 50 + 5 = 55 TK
