Question

luxmi sold two sarees for rs2185 each. on she lost 5%,while on the other she gained 15%. find her gain or loss percent In whole transaction

Answer 1

first saree

s.p=Rs2185
loss%=5%
C.P=[100/100-loss%*S.P]
C.p=[100/100-5*2185]
C.P=RS 2300

Second saree
S.p=2185
profit=15%
C.p=[100/100+profit%*C.P]
C.P=[100/100+15*2185]
C.P=RS 1900

Total C.P=2300+1900
               =Rs 4200
Total S.P=2185+2185
               =RS 4370
IF S.P>C.P then profit
S.P=S.P-C.P
      =4370-4200
      =Rs 170

Profit%=[profit/C.p*100]
             =[170/4200*100]
            =4.047%
