Answer 2

B sells it to C at loss of 20%. that means 520 is 80% of the B paid to A.
suppose PB is the price B paid to A.
0.8 PB = 520
PB = 650
so the answer for number 1 is $650

now suppose PA is the cost price of A
A sells bicycle to B at a profit of 30% , that means the cost price of B is 130% the cost price of A
1.3 PA = 650
PA = 500
so the answer for number 2 is $500
