Question

1) A sells a bicycle to B at a profit of 20% and B sells it to C at a profit of 5%.
If C pays Rs.3780, what did A pay for It?

Answer 1

first we will find how many did the B pay for the bycycle:-
=S.P of B -5℅ of S.P of B
=3780-5/100×3780
=3780-189
=₹3591
S.P of B=C.P of C=₹3591

now to find the C.P of A
S.P of B-20% of S.P of B
=3591-20/100×3591
=₹2872.2

The C.P=₹2872.2
