b) Detergent	$1$ packet	$371$	$371$	$22.10\%$
c) Namkeen	$1$ packet	$153$	$153$	$18.30\%$

Find the total amount of the bill she has to pay.

Answer 1

As per question,
(a)Rate of $1$ packet wheat flour $=Rs.200$
Discount $\%=16\%$
So, the cost price $=Rs.(200-\frac{16}{100}\times 200)=Rs.168$

(b)Rate of $1$ packet detergent $=Rs.371$
Discount $\%=22.10\%$
So, the cost price $=Rs.(371-\frac{22.10}{100}\times 371)=Rs.289$

(c)Rate of $1$ packet namkeen $=Rs.153$
Discount $\%=18.30\%$
So, the cost price $=Rs.(153-\frac{18.30}{100}\times 153)=Rs.125$

Net amount of the bill she has to pay $=$ price of wheat flour$+$ price of detergent $+$ price of namkeen
$=Rs.(168+289+125)$

$=Rs.582$

Hence, she has to pay $Rs.582$
