Correct option is (d) 14 %
Let the M.P. = Rs. x.
Then the S.P. after a discount of 9% = Rs. \((x - x\times \frac 9 {100}) \) = Rs. \(\frac{91x}{100}\)
But the S.P. = Rs.25935
\(\therefore\frac{91x}{100} = 25935\)
⇒ x = Rs.25935 × \(\frac{100}{91}\)
= Rs 28500
= M.P.
Now he gets 3.74% profit by selling it at Rs. 25935.
\(\therefore\) The C.P. = \(\frac{S.P \times 100}{100+ profit}\)
= \(\frac{25935\times 100}{100+3.74}\)
= Rs. 25000
So, profit, when the S.P.is Rs. 28500 = Rs.(28500 − 25000)
= Rs.3500.
\(\therefore\) Profit = \(\frac{3500 \times 100}{25000}\) = 14%
