Question

2. A man sold a radio-set for 250 and gained
one-ninth of its cost price. Find :
(i) its cost price; (ii) the profit percent.​

Answer 1

Answer:

(i)selling price of Radio set = $250

cost price of Radio set = X

X = 250 - X/9

9X = 2250 - X

10X = 2250

X = 225

cost price of Radio set = $225

(ii)profit percent

% = 25(100)/225

= 2500/225

= 11.11%

Profit percent = 11.11%
