Given
The cost of leather coat is ₹$2,654$
The rate of sales tax $9%$
Calculation,
Let, the reduced price if coat be$y$
Total amount of the coat $=y+9%$of
$=1y+\left( 9/100 \right)y$
$=109y/100$
But, the total amount of the coat to be paid = ₹$2,616$
Then reduced price , $109y/100=$₹$2,616$
$y=(2,616\times 100)/109$
$y=2,61,600/109$
$y=2400$
