1. Answer:

   Let M.P be x

   then discount=20%ofx

   100

   20

   ×x=

   5

   x

   S.P=M.P-discount

   x−

   5

   x

   =

   5

   4x

   But given S.P=1440

   5

   4

   x=1440

   x=

   4

   1140×5

   x=1800

   Profit=S.P-C.P

   25%ofC.P=1440−C.P

   4

   1

   C.P=1440−C.P

   4

   1

   C.P+C.P=1440

   4

   5

   C.P=1440

   C.P=1140×

   5

   4

   C.P=1152

   So,M.P=1800andC.P=1152
