Ex 7.2, 8 Amina buys a book for Rs 275 and sells it at a loss of 15%. How much does she sell it for? C.P = Rs 275 S.P = ? Loss Percentage = 15% πΏππ π /(πΆ.π) Γ 100% = 15% πΏππ π /275 = (15%)/(100%) Loss = 15/100 Γ 275 Loss = 4125/100 Loss = Rs 41.25 Now, Loss = CP β SP S.P = C.P β Loss = Rs 275 β Rs 41.25 = 275 β 4125/100 = (27500 β 4125)/100 = 23375/100 = 233.75 Thus, she sells it for Rs 233.75
