Answer 2

Answer:

Step-by-step explanation:

Abel:

Cost price = $ 600

Loss = 20%

Selling price = $\frac{100-loss}{100}*Cost \ price$

                     $= \frac{(100-20)}{100}*600\\\\=\frac{80}{100}*600$

                     = 80 * 6 = $ 480

Cost price for Bob = Selling price of Abel = $ 480

Bob's cost Price = $480

Selling price = $\frac{100+Profit}{100}*CP$

                     $= \frac{100+5}{100}*480\\=\frac{105}{100}*480$

                      = $ 504

Amount paid by Charles =$ 504
