Question

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

Answer 1

Step-by-step explanation:

(i)Let the cost price be x

According to question,

x + x/9 = 250

10x/9 = 250

10x = 250 X 9

10x = 2250

x = 2250/10

x = 225

(ii)Profit = 1/9 X 225 = 25

Profit% = 25/225 X 100 = 100/9 = 11.11%

Hope it helps you!
