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

Vimal used the formula method:
Discount =10%, Gain =20%,
C.P. = 450, M.P. = ?
M.P. =

(100−10)
(100+20)
×450
=

Answer:-
m.p. = 600
Explanation:-
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
