10. If the cost price of 11 shirts is equal to the selling price of 10 shirts, find the percentage profit or loss.​

Answer»

Answer:

The shopkeeper gets profit and the profit percent is 10%.

Step-by-step EXPLANATION:

Let cost price of one SHIRT be RS x.

GIVEN

The cost price of 11 shirts is equal to the selling price of 10 shirts.

  • Then, Cost price of 11 shirts = Rs 11x
  • Selling price of 10 shirts = Rs 11x
  • Selling price of one shirt = Rs 11x/10 = Rs 1.1x

WE HAVE

  • Selling price of one shirt = Rs 1.1x
  • Cost price of one shirt = Rs x

HERE

  • Selling price is greater than the cost price as Rs 1.1x is greater than x.

THEREFORE, Profit

FORMULA USED

  1. Profit = SP - CP
  2. Profit percent = (Profit × 100)/CP %

Where,

  • Selling price = SP
  • Cost price = CP

FINDING THE PROFIT

  • Profit = SP - CP
  • Profit = Rs (1.1x - x)
  • Profit = Rs 0.1x

FINDING THE PROFIT PERCENT

  • Profit percent = (Loss × 100)/CP %
  • Profit percent = (0.1x × 100)/x %
  • Profit percent = 10x/x %
  • Profit percent = 10%
