उत्तर

Formula for discounted price L.W = `"Marked price" ("M.P") xx ((100 - "d"%))/100`

When d is the discount %

∴ D.P = `"M.P" xx (((100 - "d"%))/100)`

School bag = `"M.P" xx (((100 - "d"%))/100)`

= `500 xx ((100 - 5))/100`

= `(500 xx 0.95)/100`

= ₹ 475

For bill amount, we should apply GST on the discounted value of the items.

Formula: Bill amount = `"Discounted price" xx (((100 + "GST"%))/100)`

∴ For School bag.

Bill amount = `475 xx (((100 + 12))/100)`

= 475 × 1.12 = 532%

∴ Total bill amount of School bag + Stationary + Cosmetics + Hair drier

= 532 + 252 + 1357 + 2304

= ₹ 4,445
