Question

A shopkeeper bought two watches for rupees 425 each he sold one of them at profit of 10% and another at loss of 10% find his gain or loss percent

Answer 1

No profit or loss (0% profit/loss)

Answer 2

Let the cost price (CP) of each watch = Rs. 425.

1. For the first watch (10% profit):

   Selling Price (SP₁) = 425 × (1 + 0.10) = 425 × 1.10 = Rs. 467.50

2. For the second watch (10% loss):

   Selling Price (SP₂) = 425 × (1 – 0.10) = 425 × 0.90 = Rs. 382.50

3. Total Calculation:

   Total CP = 425 + 425 = Rs. 850

   Total SP = 467.50 + 382.50 = Rs. 850

Since Total SP = Total CP, there is no overall profit or loss (0% profit/loss).
