Answer:

Vanitha used this method:

Let M.P. be 100.

Discount =10% of M.P.

=

100

10

of M.P. =

100

10

×100

= 10

S.P. = M.P. − Discount

=100−10= 90

Gain =20% of C.P.

=

100

20

×450= 90

S.P. = C.P. + Gain

=450+90= 540

If S.P. is 90, then M.P. is 100.

When S.P. is 540,

M.P. =

90

540×100

= 600

∴ The M.P. of an article = 600

OR

Vimal used the formula method:

Discount =10%, Gain =20%,

C.P. = 450, M.P. = ?

M.P. =

100−Discount%

100+Gain%

× C.P.

=

(100−10)

(100+20)

×450

=

90

120

×450

= 600
