Plz answer this question fast its very urgent.
9 and 12

Answer 1

9) Let the cost of each chair be x.

Let the sp of each chair be y.

Now 

10x = 16y.

x = 16y/10 = 8y/5

 

As Sp is less than cp so there is loss.

So

Loss %  is   CP-SP/CP  * 100

Cp is x = 8y/5 and Sp = y

Loss is 8y/5-y / 8y/5 * 100 = 37.5%.

So there is a loss of 37.5%

12) Dear Student,

Selling price of scooter = Rs. 35000

Profit = 25%

Cost price of scooter = 
CP = 
CP =  
CP = Rs. 28000

Loss = 25%

CP = 
CP = 
CP = 
CP = Rs. 46666.67

Total CP = 28000 + 46666.67 = 74666.67

Total SP = 35000 + 35000 = 70000

Here, CP > SP hence there is a loss

Loss% = 
          = 6.25 %
