(d) 103/9 %

Answer 1

option c. ........ 100/9%

Answer 2

Answer:

option (b) is correct

Step-by-step explanation:

Let the cost price of an article be Rs. x

Let the selling price of an article be Rs. y

As per given data,

C.P of 10 articles = S.P of 9 articles

10x = 9y

profit = S.P - C.P

profit = y - x

profit = (10x/9) - x

profit = x/9

profit percentage

$= \frac{profit}{C.P}(100) \\\\= \frac{\frac{x}{9}}{x}(100) \\\\= \frac{100}{9}$

Profit percentage = 100/9 %
