Answer 2

The effective discount is 9.25%

Step-by-step explanation:

Consider the provided information.

The cost of cookies box is RS 1000 and the cost of chocolate bar is RS 400.

We buy 2 boxes of cookies and 3 bars of chocolate.

Amount which we need to pay without discount is:

1000×2+400×3=2000+1200=3200

We need to pay Rs 3200 without discount.

It is given that A Rs 1000 box of cookies is offered at 10% discount and a Rs 400 bar of chocolate at 8% discount.

After getting 10% on 2000 we need to pay: $2000\times\frac{90}{100}=1800$

After getting 8% on 1200 we need to pay: $1200\times\frac{92}{100}=1104$

Total amount after discount need to pay: 1800+1104=2904

Hence, the saving is 3200-2904=296

Therefore the effective discount percentage is:

$\%=\dfrac{296}{32}\times100= 9.25\%$

Hence, the effective discount is 9.25%
