Answer 2

Answer:

(a)320

(b) 1710

Step-by-step explanation:

2(a).

Given selling price =360                           

Gain%=12.5%                                                       

We know, cost price = selling price × 100/100 + gain%        

            

Therefore,

cost price =

360× 100/100 + 12.5                            

  = 360 × 100/112.5                       

  = 36000/112.5

=320

                                           

Therefore, the cost price of the bag is 320.

2(b).

Given selling price=1539                      

loss%=10%                                                       

We know, cost price = selling price × 100/100-loss%        

            

Therefore,

cost price =

1539× 100/100 - 10                          

  =1539 × 100/90                     

  = 153900/90

=1710

                                           

Therefore, the cost price of the bag is 1710
