Step-by-step explanation:
Let the C.P of A be 100.
Given that A sells a bicycle to B at 20%. Then the cost price of B = 100 + 20% of 100 = 120%.
Given that B sells a bicycle to C at 5%.Then the cost price of C = 120 + 5% of 120 =120 + 6 = 126.
Given The cost price of C = 3780
If 126 = 3780
1 = 3780/126
100 = (3780 * 100)/126
= 3000.
Cost price of A = 3000.
Hope this helps!

selling price of B =₹1890
he made a gain of 5%in it
of the cost price of B = 100/100+5*1890=₹1800
the selling price of A = the cost price of B
the cost price of A = 100/100+20*1800= ₹1500
so the cost price of A ₹1500(ANS)
