Question

SALMAN BOUGHT 40 CHAIRS AT RS 175 EACH. HE SOLD 10 CHAIRS AT A LOSS OF 8%. AT WHAT PRICE MUST HE SOLD THE REMAINING CHAIR 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

Answer 2

Answer:

203

Step-by-step explanation:

cost of 10 chairs =10×175

=Rs.1750

S.P =  

100

[C.P(100−loss%)]

​  

 

=  

100

1750(100−8)

​  

 

=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

=Rs  

30

6090

​  

 

=Rs. 203
