Question

Salman bought 40 chairs at Rs175 each. He sold one-fourth of them at a loss of 8%. At what price each must he sell the remaining chairs so as to gain 10% on the whole deal?

Answer 1

cost of 10 chairs= 10 × 175
                          = Rs. 1750
S.P=[C.P(100-loss%)]/100
      = 1750(100-8)/100
      =17.5 × 92
      = Rs.1610
loss=140
total C.P=40×175=7000
10% profit= Rs.700
C.P of 30 Chairs=30×175=5250
S.P of 30 chairs=5250+700+140
                         =5950+140
                         =6090
S.P of 1 Chair for getting 10% on whole day=6090/30=Rs.203
