Answer:

3. i. Cost Price = Rp 3000

ii. Cost Price = Rp 2475

Step-by-step explanation:

i. The formula for finding the cost price given the selling price and gain % is:

       

                                  CP =   \frac{(SP * 100)}{(100 + Gain Percent)}

                                  CP =   \frac{(3150 * 100)}{(100 + 5)}

                                  CP = 3000

ii. The formula for finding the cost price given the selling price and loss % is:

                                  CP =   \frac{(SP * 100)}{(100 - Loss Percent)}

                                  CP =   \frac{(1980 * 100)}{(100 - 10)}

                                  CP = 2475

                                                                     Hope this helps! :)
