Correct Answer: The retailer's margin is INR 2,54,000
Solution :
Given that the amount spent on printing is INR 1,40,000
Let the total cost be $x$
According to the given pie chart,
Cost spent on printing = 12.5% of $x$
⇒ $140000=\frac{12.5}{100}\times x$
⇒ $x=\frac{140000\times 100}{12.5}$
⇒ $x=$ INR 11,20,000
Now, cost of paper = 15% of INR 11,20,000
= $\frac{15}{100}\times 1120000$ = INR 1,68,000
And, Cost of editing = 7.5% of 11,20,000
= $\frac{7.5}{100}\times 1120000$ = INR 84,000
Also, Retailers Margin = 22.5% of 11,20,000
= $\frac{22.5}{100}\times 1120000$ = INR 2,52,000
And, Cost of Transportation = 10% of 11,20,000
= $\frac{10}{100}\times 1120000$ = INR 1,12,000
$\therefore$ The statement which is not given correct = Retailer's margin is INR 2,54,000
Hence, the correct answer is 'Retailer's margin is INR 2,54,000'.
