Answer 1

let C.P. for Mr. A =x
profit of A=20% of x=20*x/100=x/5
he sell it to B at= x+x/5=6x/5
profit of B=25%of 6x/5
=(25*6x)/5*(100)
3x/10
B sell it to C at=(6x/5)+(3x/10)
=15x/10=3x/2 =1500 (which is given in ques)
3x=3000
x=1000

Answer 2

1500×25÷100
1500×1÷4
375
so,
1500-375
the mr.b sold to mr.c at 1125
1125×20÷100
1125×1÷5=225
1125-225=900
the mr.a sold to mr.b at rs.900
