Answer 1

Answer:

Given -:

A bought a book for 600 and sold it to B at a

profit of 10%. B in turn sold it to C at a loss of

10%. The price at which C bought the book was:

To find -:

The price at which C bought the book.

Solution-:

C.P of A = Rs. 600

S.P. of A = 600×(10/100)

$= 6 \times 10 = rs.60$

$S.P=600+60=rs.660=C.P of B$

$B \: sold \: this \: book \: which \: he \: bought \\ \: at Rs.660 \: at \: a \: loss \: of \: 10\% to \: C.$

$C.P of C = (100-10)\% of \: 660$

$C.P of C = 660× \frac{90}{100} = 594$

Thus,C should pay Rs.594 to bought the book.
