$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Hey Mate!!!}}}$

Here is your answer

MP = Rs 13500
Discount = 6%

Discount = 6% of 13500
$= \frac{6}{100} \times 13500 \\ = 810$
SP = 13500 - 810
= 12690

Profit% = 25%

As we know the formula

CP = SP × 100/(100+PROFIT%)

$= \frac{12690 \times 100}{(100 + 25)} \\ \\ = \frac{1269000}{125} \\ \\ = 10152$

Therefore Cost price of Piano is Rs 10,152
