बेरीज

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)`

Hair dryer = `"M.P" xx (((100 - "d"%))/100)`

= `2000 xx (((100 - 10))/100)`

= 2000 × 0.9

= ₹ 1,800

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

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

∴ For Hair drier,

Bill amount = `1800 xx (((100 + 28))/100)`

= 1800 × 1.28

= 2304

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

= 532 + 252 + 1357 + 2304

= ₹ 4,445
