plz slove the Q 4 please

Answer 1

Answer:

0.25%

Step-by-step explanation:

Total Selling price = 7980.

(i) Gain = 5%

∴ Cost price of first cooler = (3990 * 100)/105

                                           = 3800.

(ii) Loss = 5%:

∴ Cost price of second cooler = (3900 * 100)/95

                                                  = 4200.

Total cost price = 3800 + 4200

                          = 8000.

Here, Cost price > Selling price. So, Loss has occurred.

Loss = Cost price - Selling price

        = 8000 - 7980

        = 20.

Loss% = (Loss/CP) * 100

          = (20/8000) * 100

          = 0.25%.

Therefore, Loss = 0.25%
