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
