Question

Amina buys a book for rupees 275 she sells it at a loss off 15%. How much does she sell it for?

pls answer the full formula

Answer 1

Cost price= Rs.275
Loss = 15%
Selling price = Cost price - Costprice*loss/100
=Costprice( 1 - loss/100)
= cost price[(100-loss)/100]
=275*[(100-15)/100] = 275*85/100 = 233.75Rs.

[Loss = CP-Sp...so SP = CP-Loss...&& Loss% = Loss/CP *100..so Loss = CP*Loss%/100]
